Well, first, I liked The Lawnmower Man. Of course, I'd previously read the book, which included much more of the science necessary to suspend belief, so I could have easily been "reading more into it" so to speak than was there on the screen. Also, there is so vastly little good Sci Fi out there (especially if you subtract the space opera), I may tend to be more forgiving than I would be if there were as many intelligent movies as there are intelligent books in the genre....
My first nominee is "To Live and Die in L.A." I actually took a 1st date to this one, and even though I got brownie points for telling her 3/4s of the way through that I couldn't take any more and we should leave, she still harassed me for subjecting her to it. It tries to be a gritty, supposedly realistic slice of law enforcement life, but it's just a stupid plot with some brutal violence that's supposed to save it because "it's realistic".
My second nominee is "1 Million Years B.C." I saw this early Raquel Welch vehicle with my cousins when I was 6 and in that pre-pubescent stage where you don't understand why you get erections in the bathtub or like looking at buxom cave-women in ultra-small fur bikinis yet, but, damn it, you do. When it came on a cable channel during late night about 6 months ago, I wondered if maybe I'd been a little backwards at 6. Raquel Welch would later do a worse job of standing around trying to look sexy because she had the acting skills of a lox, but she was never again surrounded by so many other bad actors and directors.
My third pick is "Xanadu". For the hell of it I watched "Saturday Night Fever" for the 2nd time (since the 70's) last year expecting to get a load of pleasantly laughable crap, and was really surprised that, despite the fact that it helped create the evil of disco, SNF was actually a really well made movie. Xanadu was what I expected SNF to be, only it was so bad that it wasn't even close to pleasantly laughable. The fact that Ms. John is still alive after foisting this on humanity constitutes convincing proof that the evil one enjoys having her around. It is no accident that Olivia released the "Let's Be Physical" video shortly after this movie's release.
Just as Satan can quote scripture, the wife of Satan, Ms. John, can act like she's virginal-but-hip, and that the blackest hole of god's universe does not reside between.... with her.
