You will all think I'm a noob, but hands down my all time favourite Anime is Digimon Tamers, closely followed by Neon Genesis Evangelion, and Kanon.
There's no shame in liking Digimon, but Kanon? o-O Surely there's much better anime in the "made from a dating game" genre.I personally love Pokemon and older mainstream shows like Tenchi, Ranma, Eva, etc. I don't really care for newer mainstream shows like Naruto and FMA.
