I’ll list some that I’ve seen that I did like since I do not have favorites. I just love anime =o. Black Butler, SnK, FMA, FMA Brotherhood, Elfen Lied, Madoka Magica, Inuyasha, Fate/Zero, Kill la Kill, Ouran High School Host Club, Soul Eater, SAO, Fairy Tail, Bleach, Blue Exorcist, Knights of Sidonia, Deadman Wonderland, Vampire Knight, and many more. If you are just getting into anime and like action, I’d say go straight for Attack on Titan since it’s a good start. If you like gore, I’d go with Deadman Wonderland or I’ve heard Tokyo Ghoul is good too. Really…all of the animes were good.
