Now that you asked, I don't like many genres... Only fighting/action, adventure and comedy animes interest me, specially if they have at least a little bit of each. Those are usually the sillies ones, but I still like it :P
For example, my eternal favorites are: Dragon Ball (including Z and GT), One Piece, Toriko (although the manga is way better), Katekyo Hitman Reborn and, a long time ago when it was good, Fairy Tail. Bleach and Naruto are good too, I guess...
Anime Genres and themes I tend to end up liking are the following:
- Slice of Life
- Romance
- Ecchi
- Action
- Martial Arts
- History
- Heart Warming Moments
- Fantasy
- And a bit more... can't remember. I need a list.
Reason to this is... look at the following picture.
-Psychological is definitely my favorite genre. Then
-Comedy (like Trigun, or Samurai Champloo)
-Horror (best when mixed with Psychological) like (Elfen Lied or Monster)
-Action (like Sword of the Stranger or Black Lagoon)
-Dark fantasy (like Berserk or Claymore)
-Adventure (like Last Exile or Berserk(manga mostly))
Well, in my case is it so, I'm most(ly) very big fan from VNs and LNs adapted anime; where I slice-of-life, comedy, horror, action also/too love, romance, dark, psycho ganre value.
There some examle animes:
- The Fate-series and with the type-moon related anime.
- D.C.~da capu seires, and such like animes.
- And Yahari ore no seishuun... like slice-of-life anime.
For me it's action, horror SF/Fantsy/post apoclypes/world war word 3, some thing along the lines of Code Geass for the action and for horror something like HighSchool Of The Dead but with half as much fan service and lots of main charaters/secondary characters dying as well as people dying in droves and a grim dark story line made for guys.
Honestly , I don't have one as long as the Chara's and art is interesting ~ I love seeing Nekomimi's and Fantasy like things though , huge attraction !!
