- I haven't seen all of 8 Seconds because I hate it.
- I haven't seen all of Grease (at least not in one sitting) because I hate it.
- I haven't seen Footloose because I fear it's going to remind me of Grease.
Pretty much the only genre of movies I don't like are ones set up as filmed stage plays. Grease, Hair, Rent, modern takes on Shakespeare, etc. That whole genre irks me. Second most hated is the genre of stupid comedies, like Shallow Hal or Scary Movie, especially if they're stupidly oversexed.
My favorite genres are historical dramas (John Adams, Pride & Prejudice, Fat Man & Little Boy, etc) followed by hard science fiction (The Man From Earth), followed by popcorn sci fi (Star Wars, Star Trek, Serenity).
I'm generally opposed to rampant sex, violence, or language, so I generally steer clear of movies rated R or worse. I will make occasional exceptions, most obviously for The Matrix. Which ruled. There are no sequels. None. Ever.
I love animation in both it's Disney-ish and Anime forms. Animation is capable of greater emotional power and persuasive influence than live action, especially in showing beauty and mystery. Pixar is the best production company ever, largely because they understand and wield that power.
In general, I love movies.
