Epic, but nope:
-Code Geass: Didn't care for the MC or his misguided justification for terrorism (Come at me bro).
-Angel Beats: Answers just led to more questions. It turned me off a little.
-Darker than black: I never finished it or watched season 2.
-School days: I hated everyone and wanted them to die.
-Higurashi no naku koro ni: Series lost its allure after the first half of season 1
-Dragon Half: Too short
-Spice & Wolf: Not enough closure
-Black Cat: Its low tier to the likes of Trigun and Cowboy Beebop.
-The manga is/was farther ahead: Gantz, Berserk, Bakuman, Fruits Basket, Hunter x Hunter, Hellsing, Claymore, Bokura ga ita, Air Gear, Tenjou Tenge
-Still ongoing and/or Too many fillers: Bleach, Naruto, Blue Exorcist
