Movies that got a lot of undeserved hate

Prometheus

I re-watched Alien a few weeks after first seeing Prometheus & I was impressed that Scott pulled it off.  I mean, the Nostromo crew stumbles over the ancient pilot & that's it.  That's it? lols  A bunch of alien goo impresses them more than an actual giant sized humanoid pilot on an entirely other world.
I think once ppl appreciate that Prometheus isn't about the Xenomorphs so much as it's about that pilot & their backstory, it settles a lot better.  
Alas, the marketing team pushed it full throttle as Alien Alien Alien Alien, when it should've been promoted as that Creator pilot's backstory coinciding with the Alien universe.  
At least they got the movie title right, because it shies away from Alien proper yes?

Spider-Man 3: I can understand why people might not like the Sam Raimi SM movies in general, but it always baffled me how so many people could call the first two films masterpieces and then hate the third one for being "too silly." That's like hating "Toy Story 3" for being a lot like the first two movies in tone. It's just a bit hypocritical. Speaking of which, while I do agree about two criticisms (Venom in this movie sucks, and that dancing scene is atrocious), everything else just feels like either nitpicking or being way too harsh on the movie for not being close to its source material. As for the complaint about the movie being too cluttered, the only real casualty was Venom. Peter, Mary Jane, Harry, and Sandman all had fully fleshed out character arcs. I just feel like people took the butchering of one character and applied it to the whole movie. Ironically, "Iron Man 2" did a far worse job of balancing multiple characters and sub-plots, but got a free pass because people really love Robert Downey Jr, I guess (so do I, but that's not the point). But at least S3 was entertaining, whereas IM2 was outright boring.

Superman Returns: Honestly, I haven't seen this one in a while, so maybe my opinion could change, but this felt like a proper third part to the classic series, as opposed to the one that we originally got. The movie had good action for the time and a decent script with a lot of heart to it. I'm mot saying that it didn't have issues, but I genuinely enjoyed it. I just never got the hate for this one.

Prometheus: Yes, this movie had some seriously stupid bits of writing in it, but not nearly as much as people made out. And really, it wasn't those scenes that everyone lingered on complaining about. The real reason that people hate this movie is because it's not what they expected. People expected a prequel to "Alien" that answered a lot of questions. Instead we got a very loosely tied-in story that in many ways was a modern take on the atmosphere and suspense from the original Ridley Scott "Alien", but that only raised more questions of its own. Personally, I loved that about the movie. It's the only other film besides the original "Alien" that had that sense of mystery and tension to its atmosphere, but which also had me completely engrossed to learn about what was going on, and really prompted me to thoroughly analyze the movie on re-watches. Any film that can make me think to that extent is worth a lot more credit than what people give this movie, IMO.

I'm going to add "Showgirls" it wasn't a great film but I don't think it was much worse than your average film about strippers either. I can't help but think there was some agenda pushing the hate machine on this one.

8mm. Somehow it carries a 22% on Rotten Tomatoes, but I consider it a neo-noir masterpiece.

Witches of Salem is truly a creepy movie. I also like the Devils Rejects and House of 1000 corpses.

Yes. It wasn't that bad. I don't get the hate either.

EYES WIDE SHUT, will just naturally gain more admirers with time as part of the Kubrick oeuvre.
BACK TO THE FUTURE II is clever, but a bit too silly and contrived compared to the classic original. It doesn't have the same heart.
DIE HARD II is my favorite of the series, so I don't get any hate directed towards this one.
WATCHMEN had cult written all over it, the day it hit the screens and while not everyone's cup of tea, it is wonderfully designed and conceptualized.

alien 3 - i can get why people don't like the awful, awful, awful theatrical cut. but the assembly cut is a very good film, or at least 9/10s of a film (unfinished special effects shots here and there). it's gloomy and depressing and completely different from the preceding films, but i still love it. it's very silly to me that the blompkammp film is going to pretend it never happened (resurrection, on the other hand, can go right into the trash bin with the AVP films)

back in like, 2008, the imdb board for alien 3 could get pretty heated, too - a few people who hated the film insisted that those who liked it were screwed-up sociopaths.
