Mostly movies;
The standard affair of Ghibli stuff; Princess Mononoke, Howl's Moving Castle, Spirited Away, Return of the Cat!, etc.
I also like some of the regular violent and lesser-known stuff; Tekkon Kinkreet, Najica, Sword of the Phantom Master, Ninja Scroll, Tenjou Tenge, Naruto, Bleach, watched some Gintama and I'm considering either watching the entirety of D-Gray man or just dumping it off my HDD.
Pretty much if it has over-elaborate violence, powerups and other such juvenile eye-wideners, I like it.
I've also watched 26 eps of Gantz, but I still don't know how I feel about that series.. It has violence, beheadings, sci-fi, onionheads, raping dogs and those big stone whatchamacallits, but there's something a bit 'off' about all of it.
