I actually don't watch that many new movies. But I think adventure movies are very nice, you have that open-ended sort of thrill. Just a guy,, a few friends, a backpack full of necessary rations, and perhaps some sort of vehicle. And a vast, interesting and beautiful landscape to explore. Fascinating, if taken well, and with a good idea.
Comedies and Actions are definately my 2 favorite genres. Maybe after those 2 would be Sci-Fi (not those stupid Sci-Fi Horrors), Adventure, and Fantasies.
I like comedies, horror, and sci-fi. I've yet to see an actually scary horror/thriller movie though. They all rely on things jumping out, and that makes you jump but it doesn't scare you.
Action movies all the way. Comedies are good too but I really like going to the theaters to see super special effects. Scary movies are better at home in the dark, maybe with a few friends.
