Began watching anime as a kid with InuYasha and Fullmetal Alchemist on TV, and recently picked it back up again with Kanon(2006). Now it's almost all I watch.
I love anime with a good tale that doesn't have too many fillers; I love stories, not twenty minute visits to the hot springs. Though many of my favorites are 12-13 episodes, the longer the better. Say no to rushed endings!
That being said Romance/Drama is my favorite, because of the Romance itself but also because that is the kind of anime that makes me feel something emotionally. I want to fall in love with my characters and really feel empathy for them. I also really love Slice of Life and Adventure, although a little fantasy to shake things up is always great.
AnoHana, Kanon (2006), Cl'annad AS and Ef are my absolute favorites I adore them. Angel Beats, Air, Kimi ga Nozomu Eien, and Haruhi are some of my other favorites. FMA: Brotherhood and Ruroni Kenshin as well (But those are obvious).
If you have any recommendations please let me know.
See you soon,
