I have a fairly extensive collection of films and TV shows on DVD (an obsession really), ranging just about all genres. I actually watch them little bits at a time, since my computer remembers exactly where I left off. I gave up trying to go to the movie theater and now just wait until a title is on DVD and either rent it from Netflix or buy it (if it is from an awesome director).
Favourite genres: horror, science fiction, anime
Favourite films: Star Wars saga (4-6 still remain the best), Metropolis (1927), Poltergeist (1982)
