i need a really great anime to watch.

I would say u should watch
- Kaze no Stigma (Romance, Comedy, Action, and magic)
- Karin (Romance, Comedy, Vampire, and Fantasy)
- Erementar Gerad (Romance, Comedy, Action, Fantasy)
That's all I can think about.

Sword Art Online (Coming out in English soon.)
Soul Eater
Black Butler (Kuroshitsuji)
Fullmetal Alchemist/Fullmetal Alchemist: Brotherhood

I try ;(

I don't watch a lot of anime, so I always recommend shows that I know have some of the genres (well, from what I see in the anime) people want.
