When people ask for recs on what to watch next people generally give the same answers (Trigun, Kenshin, Hellsing), but there's lots of other good if less popular anime out there. Every once in a while I'll run across something that will make me say, "WHY HAVE I NEVER HEARD OF THIS BEFORE!? THIS KICKS ASS!"

I kind of randomly came across 1. Kare Kano and 2. Haibane Renmei, but both turned out to be really excellent. If you have suggestions for other stuff that you think is underrated and shouldn't be overlooked please add, and try not to repeat too much, k?

I would also reccomend:
3. Condor Hero (released by live-evil (their Naruto joke-sub is kind amusing too)), an old-fashioned kung-fu anime
4. Key the Metal Idol (rated R)
