Restricting it to movies that were supposed to be good (good casts, popular with some good reviews, etc.), and which others may like.
Contact - dreadful Jodie Foster/Matthew McConaghey space disaster (South Park had an episode where the mere mention of the movie induced vomiting - I applauded)
Ocean's 12 - just for the scene where it becomes a plot line that the Julia Roberts character looks like Julia Roberts. Loved 11, and 13 was a good bounce back.
Blair Witch Project - to be fair, it was a cheap indy and they probably never thought it would become a phenomenon. For that kind of hype, you expect it to deliver something other than seasickness.
Sports category: Jerry Maguire. Especially annoyed that Cuba Gooding gets knocked out cold, wakes up, and starts doing sophisticated end zone dances. The athletic trainers would have carted him off for precautionary reasons. At that point of the movie, I had had enough anyway.
The Last Boy Scout: Bruce Willis trying to be a Die Hard-type character with a terrible script. Movie starts with an NFL player pulling out a gun, shooting all the defenders on the way to the end zone, and shooting himself in the head. Started out awful, and went downhill. (Hudson Hawk was much maligned, but that one actually cracked me up).
All flawed movies but that is some irrational hatred! Especially the bit about re The Last Boy Scout. But I guess that's what this thread is about. Not the objectively worst movies you've seen. The ones that just set you off for whatever reason.
I saw parts of Jerry Maguire this weekend and we were all laughing about how the guy potentially suffers a neck/spine injury, but (a) no doctors come on the field (b) the trainers do nothing but CLAP in his face, and (c) when he regains consciousness, nobody puts him in a brace and on a board, and (d) they allow him to prance around and break dance.
Also, Jerry does not love Dorothy at all and it's just a matter of days before he remembers that. All that said, I sure as s*** don't hate the movie.
Now let's see.
Here are some movies I hate:
Mystic River - This movie sucks. Sean Penn mopes and whines the entire movie. The plot sucks. The ending sucks. Everyone overacts. The Academy should have closed down after handing Penn that Oscar. Oh, also, the subplot with Kevin Bacon's wife was so ducking stupid it makes me angry thinking about it. (Screenwriter 1: "Should we leave in this subplot where Kevin Bacon and his wife are on the phone with each other even though it doesn't move the plot forward one iota?" Screenwriter 2: "Yes, but only if we film it by using close-ups on her mouth." Forgive me I'm not depicting this correctly; I saw it in the theater and refuse to ever watch it again.)
Crash - I didn't hate it after I saw it, although I did find it too "on-the-nose" and I also found it ironic that it was a movie about different kinds of people and prejudices yet happened to be the whitest movie ever. But I started hating it when it beat out Brokeback Mountain. I hate it less now that Haggis is no longer a Scientologist, but just a little bit.
Strictly Ballroom - I saw this on an airplane once and will never watch it again. Considering how many terrible movies I've seen on airplanes, this one must have really stuck in my craw for it to stand out like this.
Southland Tales - I loved Donnie Darko, so I was so excited to see this. I was actually laughing out loud throughout (it's not a comedy) and would have walked out had I been alone. The only scene I liked was the one that everyone else hated (Justin Timberlake mouthing the words to the song by The Killers). This was a terrible, terrible movie.
