Thanos succeeds for his goals obtaining all infinity stones, and kills half the universe using the Infinity Gauntlet. Its not common that a Villain wins in a movie, this is a standout feat for a Villain winning with what Thanos accomplished in the Avengers Infinity War Part 1 for his main goal , also 1 of the saddest endings for a movie with the Villain winning.

Thanos has seen in the past a Planet overpopulated so its unsurprising that fearing that History will repeat itself for the Universe he decides to use the Infinity Gauntlet to kill half the population in the Universe so the Universe wont overcrowd. He knows this is a destructive dreadful action but is convinced he is a Hero or Good Guy because of his twisted logic, and believes that the ends justify the means when its beneficial for a Planet or the Universe.
Even though he believes hes a Hero or a Good Guy he is using destructive dreadful methods to accomplish his goal to prevent the Universe from overpopulating which is why he is a Simple Villain meaning no ambiguity thats what the character is. 
A Simple Villain can be a believable 3 dimensional character including having believable reasons why they believe they are a hero and in the right which is what Thanos is in this movie.

In the 1st scene of this movie Hulk was winning for a short period when fighting Thanos except Thanos adjusted stopped getting hit then easily smashed the Hulk, picked him up and easily throws him on the ground.
Ebony Maw and the other 3 members of the Black Order are all shown in several different scenes as formidable adversaries in other words all get a chance to shine and are done justice.
Foreshadowing for Ms.Marvel because for the after credits scene shown on the screen of communicator that Nick Fury used is the Ms.Marvel symbol.

To many terrific memorable lines to list all of them.
 Doctor Strange insulting Iron Man about his head since he sees he has a huge ego with how does he fit his head in that helmet, Doctor Strange saying about seeing a specific scenarios he saw them winning one which highly possibly happens in Infinity War Part 2 , Spider Man fears he has a alien in his body and is describing the chest burster from the Alien movie series, Thanos saying in response to Lokis offer with a smartass remark If you consider failure experience., Thanos to Loki before killing him No resurrection this time. obvious reference to Loki resurrected from the past MCU movies, Tony Stark And I swore off dairy, but then Ben and Jerrys named a flavor after me in response to Wongs line about we meaning the Good Sorcerers swore an oath to protect the time stone with our lives, Doctor Strange in response to Tony Stark what is your job exactly making balloon animals Protecting your reality douchebag.

The movie has believable drama involving the super heroes it isnt forced or contrived, disagreement that Vision should be killed to destroy the mind stone so Thanos cant obtain it, Iron Man not wanting Spider Man involved in this fight since he could highly possibly get killed, both of them arguing why he is on that Space Ship, etc.
The decent funny gag is Thor repeatedly calls Rocket Raccoon a rabbit that doesnt get correct saying that is a Raccoon not a rabbit.
Drax believes he is invisible obviously he isnt which was funny because Praying Mantis saying he can see him, Thor repeatedly calls Rocket Raccoon a Rabbit and Rocket Raccoon doesnt correct him neither do the other GOTG, Spider Man talking about chest bursters of the Alien movie series fearing he might have a alien in his body, etc these movie as usual has funny scenes and lines.
Impeccable timing with Captain America walking out of the Shadows also Falcon and Black Widow that fight 2 members of the Black Order that after seeing the futility retreat failing to remove the mind stone from Vision.
Also logical that Star Lord, Drax, and Praying Mantis fighting Spider Man, Doctor Strange, and Iron Man because they decided to start fighting rather than ask questions, and they dont know who exactly these persons are, when important information gets exchanged the fight ceases.


Unique Stan Lee cameo as a bus driver the 1 Peter Parker is on, I dont recall Stan Lee as a driver in the other Marvel Movies so something unique and new.
Great intentional irony Spider Man saying it doesnt make sense for the whole he cant be a friend neighborhood Spider Man without a neighborhood because it is sensible with no neighborhood Spider Man cant be a friendly neighborhood Spider Man.


This movie finds a logical way to use all its locations including Scotland because the Infinity Stones are in those locations.
Also Scarlet Witch, Captain America, Thor, Spider Man, Doctor Strange and all other super heroes get a chance to shine in the action scenes since the super heroes are in different areas, in the fight scene in New York City Iron Man, Spider Man, and Doctor fighting members of the Black Order. When the Hulk fought Thanos that was the only fight shown, Doctor Strange fights Thanos, Scarlet Witch shown fighting monsters in the fight in Wakanda and killing a member of the Black Order, etc.
Even in the Climax in Wakanda the super heroes are in different areas.
1 of the best action scenes is Thor using his Stormbreaker a big axe with instant teleportation, the stormbreaker that is spinning hitting monsters , and hits the ground creating a great shockwave that hits more than a dozen monsters, and does stab Thanos with the Stormbreaker axe forcing Thanos to teleport which while not a kill is still a defeat since he retreated.
Impeccable timing with Thor, Groot, and Rocket Raccoon arriving in Wakanda since the Avengers and others were getting overwhelmed by the monsters.
Rocket Raccoon and Groot are shown fighting and defeating the monsters.
Another great action scene is Doctor Strange fighting Thanos because Doctor Strange is able to multiply himself, all Doctor Stranges throw a magical lasso which around Thanos, and while he didnt succeed to defeat Thanos because he escapes it still was creative and valiant.

Great use of the Reality Stone since Thanos does alter Star Lords guns ammo to bubbles, he fools Gamora that she killed Thanos which is shown to be a illusion and moving in a side direction the illusion area is removed and the real damaged area is shown, when Thanos is talking to Doctor Strange to explain his motivations including why he wants to use the Infinity Gauntlet moving again in a side direction the environment or area is changed.
Even though Thanos is a Simple Villain a Nefarious Villain he is still believable 3 Dimensional character not a Saturday Morning Cartoon Villain.
 He saw that Gamoras planet was overpopulated with persons having to fight for scraps. His solution to fix that problem is murder all persons which he calls Mercy, the only person not killed was Gamora because Thanos has the intent to make her a disciple. 
Red Skull told him the Great Price of how a person can obtain the Soul Stone a sacrifice with a person killing the person he or she loves the most a soul for a soul, Thanos does cry before killing Gamora by pushing her off the edge.
Also Thanoss plan with the Infinity Gauntlet convinced its just and right with persons being killed rich, poor, old, young with it being random so Earth and other planets wont be overpopulated. 
Similar to Ego he is a understandable character that has good goals except his methods the same as Ego are messy, awful and destructive.
Captain America proves again hes a Pure of Heart Hero since he outright says we dont trade lives objecting to kill Vision to destroy the mind stone.
Great to finally see the Red Skull 7 years later because hes wearing a Black Hooded Robe that made me mostly think of Sith Lord specially Darth Maul since he also has that scary red face. He gives Thanos the information about the soul stone including the great undesirable price to obtain the soul stone.
The MCU is set in the same year the movies get released if any doubt before now none because Iron Man talks about events of the The Avengers with saying 6 years which would be 2012 since this is a 2018 movie.
Scarlet Witch is shown to be Noble and Valiant. She didnt want to kill Vision which she does outright say, and seeing Thanos is in the area she does kill Vision when necessary to save half of the Universes population and preventing Thanos from obtaining the final mind stone. Scarlet Witch did what was necessary which was one of the toughest actions because what it involved for her to save half of the Universes population.
Even though Thanos is still able to rewind time to obtain the Mind Stone it doesnt remove or erase Scarlet Witchs valiant noble action.
Thanos is shown to be a Ruthless Nefarious Villain in this movie. He was responsible for killing most Asgardians , he didnt have to kill Loki but does with saying no resurrection this time, he didnt kill Gamora because he would train her to be a disciple with all other persons on Gamoras planet killed calling it Mercy because overpopulated and persons having to fight for scraps, he could have decided to give up to obtain the Soul Stone because its a great undesirable price but didnt choosing to kill his daughter pushing her off a edge to obtain the Soul Stone, he had no damn problem torturing Nebula to convince Gamora to tell him important information with Gamora having to watch the physical torture of her sister, Scarlet Witch did kill Vision to prevent Thanos from obtaining the Mind Stone and Thanos without hesitation rewinds time easily knocks Scarlet Witch down and enjoys giving Vision a inhumane death by removing the mind stone to achieve his goal to obtain all infinity stones.
Thanos uses the Infinity Gauntlet with Spider Man, Doctor Strange, and others dying altered to dust, and half of the population in the Universe die because of Thanos using the Infinity Gauntlet.

A cliffhanger ending that leaves you wanting to see part 2 with Thanos has the Infinity Gauntlet, and is recovering on a Planet.
Doctor Strange did say he saw 1 scenario where they won so highly possible that gets shown in Avengers Infinity War Part 2.
