TV: I prefer series with story arc focus, strong characters and psychological focus. I am a sucker for highly intelligent characters. My absolute favorite series are Battlestar Galactica, Dexter and Prison Break (two first seasons). I would also like to mention the anime Death Note. I have a broad taste though, and I have seen all episodes of for example Sex and the City, Grey's Anatomy, Gilmore Girls... Strong series as well. Not a fan of crime series though, but that could just be a language thing, I find them difficult to follow without subtitles.
Movies: Very broad taste. Again a sucker for intelligent characters though, so among my very favorite movies are Amadeus and Good Will Hunting. I usually prefer modern movies though, although I just recently saw Psycho and Rear Window by Hitchcock, both of which were brilliant, and very psychological, to my taste. It's almost easier to ask what I don't like, and I guess I am not a huge action fan. Of course I love many action movies, but action without the psychological element being quite prominent is usually boring. The Godfather I & II are among my absolute favorite movies, but otherwise I am not too fond of mafia films, and I wasn't particularly impressed by Goodfellas, for example. A few unmentioned favorites are Léon, American Beauty, Amélie, Requiem for a Dream, Pan's Labyrinth, Oldboy, Kill Bill, Little Miss Sunshine, Before Sunrise/Sunset, WALL·E, Fight Club, The Silence of the Lambs, Raiders of the Lost Ark, The Shawshank Redemption, Forrest Gump, A Clockwork Orange, Eternal Sunshine of the Spotless Mind, Sin City, V for Vendetta, Mononoke-hime, Edward Scissorhands. There is just too much, isn't there?
Books: Not huge on reading, but mostly some sci-fi and fantasy.
