OK - I liked (no, LOVED) Napoleon Dynamite.
I also really liked Natural Born Killers.
Whenever I tell a group of people this, I invariably get looks of horror and much murmuring and averted eyes.
Now - I also have always been very bored by Last of the Mohicans (I always fall asleep about the time they are all sweating in that dark cabin discussing something by firelight, who knows what - and wake up right as the girls are throwing themselves over the cliff).
When I tell people this, I sense immediately that they consider me a very shallow person who probably doesn't give a fig about history. Actually I am a history fanatic and I really love that particular era. I don't know - I just think the movie is BORING. Of course, how would I really know - I've never actually been able to stay awake through it.
One of the few movies I have ever just gotten up and walked out of in the theater was The Good Shepherd. Honestly - that was one of the most boring and tedious movies I've ever tried to watch. Finally I realized, "I don't even care what happens to anyone in this movie and I have better things to do with my time." Surprisingly, my husband agreed with gusto and we both just jumped up and walked out.
Someone actually said to us on the way out, "Don't you want to know what happens?" and we laughed and said together, "Well, no, not really."
