Gonna be honest..... wasn't my favorite.
The first hour or so feels like it's going a million miles an hour. After a short while I really felt like it needed to slow its pace dramatically. Fast dialogue - fast dialogue - explosion - actions scene - more fast dialogue - more action. Pretty poor pacing for the entire first hour IMO. And his friend/sidekick is nothing short of terribly annoying. His repeated attempts at humor fall flat over and over again. The action/humor of this movie all just feels a bit "slapstick"
It makes a pretty strong turnaround in the second hour. It slows a bit, gives Peter Parker a little time to develop, then slowly introduces you into a bit more action.
It definitely has its bright points. Tom Holland really does make a great Spider Man. Keaton is always good. Tony Stark/ Iron Man is great, but is in the movie a lot less than I thought he would be.
Ultimately, this felt like a kiddie movie. Pretty shallow storyline, went more for the "Ooooh's and Ahhhh's" than developing a new character in the MCU. Overall I just feel like the timing was bad here. At this point in the world Captain America is a wanted criminal, the Accords have caused a massive division among The Avengers. I don't think a kid-oriented popcorn summer blockbuster fits well in the MCU right now.
In all fairness, I did see Wonder Woman like 2 weeks ago. That's a tough act to follow. I would put this near the bottom of the MCU movies. Go see it, its a fun movie, but I think it will be forgotten sooner than later.
