[Dragonheart]

as mreaper said there are a lot of threads like this in general anime section.

but still i wud put some of my recommendation here:

gungrave (highly recommended)

katekyoshi hitman reborn ( starts off with some insignificant yet funny episodes, gets better after episode 20. its very good)

code geass (kind of like death note. though it has mecha in it. but if u liked death note u wud love this one)

D.grayman ( great story line and fight)

hajime no ippo or eyeshield 21 ( if u like sports anime )
