Post really good animes to watch.

Horror: Higurashi No Naku Koro Ni/ Higurashi No Naku Koro Ni Kai, Another, Mirai Nikki, Chaos;Head, Deadman Wonderland, Elfen Lied
Comedy: Boku Wa Tomodachi Ga Sukunai, Baka To Test, Kaichou Wa Maid Sama, Inu x Boku SS (Really funny, romantic but has sad and touching moments in the last episodes).
Drama/Romance: Clannad/Clannad Afterstory (Really funny at some parts, really really sad in others), Angel Beats! (Supernatural too and Comedy), Myself;Yourself (with lots of comedy in the first part of the series like the first 5 episodes, but then it's really sad)
aléatoire animé with lots of elements in them: Code Geass: Lelouch of the Rebellion/ Code Geass Lelouch of the Rebellion R2, Loveless (has shounen ai in it, so if it's not your taste then idk), Pandora Hearts, Kuroshitsuji/ Kuroshitsuji II, Amnesia.
