I usually check reviews and ask around before I see a movie and I'm fairly picky about what I watch. But for some unknown reason, I watched these movies and HATED them.
The Nutty Professor II: The Klumps (even worse than the first)
Someone Like You (worst romantic comedy I've seen and there are SO many bad ones out there. And I love the Hugh Jackman but I hated his character.)
The Apartment (I don't care if it won the Oscar for best picture that year, it is not enjoyable. It has a 93% rating on Rotten Tomatoes and 8.4 out of 10 on imdb but I just have to disagree. I also feel this way about Vertigo, though not as strongly.)
An American Haunting
The Waterboy - I have to really be in the mood for Adam Sandler or Will Ferrell and I wasn't when I saw this.
Miss Congeniality - I'm sorry if you liked this, I wanted to, but I did not find it amusing.
Casino Royale (1967) - a horrendous James Bond parody
Honorable Mentions:
.Twilight (But I will try not to judge you if you like it. I did enjoy the book. I also hated the 2nd movie, but I saw it because someone convinced me it was better than the first. It wasn't. I will not be seeing the others.)
.Never Been Kissed (one of many romantic comedies that sicken me, including Kate & Leopold, How to Lose a Guy in 10 Days and A Walk to Remember)
.Hellboy
.The American (why George Clooney, why?)
.The Producers (1968)
.Armageddon
.District 9
.Mama Mia!
.Paycheck
.Equilibrium
I also find Austin Powers and Dumb and Dumber, more irritating that humorous.
