I want to watch a good anime i havent seen?

Have you watched Death Note?? it's REALLY good (mostly action and intrigue but it's really mental, i think you'll like it), and D-grayman too... what else? Black cat, even though i just read the beggining of the manga, but i liked it if it's for comedy and action.... if i think of anything else i'll let you know. Haven't seen nightwalker but some ppl have strongly recomend it, it's a clasic! and shaman king is another clasic that i strongly recomend if you're looking for action and comedy
