I voted comedy, but I also like sci-fi, and most other genres to some extent. One of my favourites is The Fifth Element, as an example.
My others are Austin Powers, The Matrix, American Pie, amongst others.
I saw Not Another Teen Movie and Eternal Sunshine the other day; the first was just so funny and the second was really well made. No particular reason why I got them both, just the video shop offers two films for A3;5.
