Movies: Not much for horror, but other than that I try to watch everything. Doesn't matter if its big budget major studio, indie or foreign. Right now my favorite directors are Wes Anderson, Guy Ritchie, and Tarantino. Also I tend to watch comedies over and over more so than dramas, particularly darker comedies. Put Nick Frost next to Simon Pegg, and guarantee I'll watch the movie.
Shows: All time favorite is Mr. Show. Current favorite is A Game of Thrones. Also Breaking Bad, Walking Dead, Community, New Girl, Big Bang Theory and How I Met Your Mother.
Music: My staples are The Beatles, The Tragically Hip, The Clash, Fugazi, Nine Inch Nails, and Neko Case. Pretty much listen to everything. I don't know if there's a genre without at least one artist/band I like in it.
