Some GooD Anime or Manga?

I don't have a whole lot of knowledge of mainstream.

I'd suggest Gurren Lagann.

Elfen Lied - one of teh best , darkest, deepest, multi messaged aniems i have ever watched do not take it for face value alone



try these though

cowboy bebop
Ghost in teh shell
ghost in the shell 2nd gig
wolfs rain
planetes
fullmetal alcehmist

also break outta the main stream crap most of it is jus the same shit repeated over and over

Thanks for all the feed back everyone. I have now started expanding my reading to other genres.
I started Fairy Tail, Hunter X Hunter, Defense Devil, and Hajime no Ippo.

I'd go with Berserk. Also try:

-Holyland
-Zetman
-Aiki
-Freezing
-Onihime VS
-Battle Royale
-Tiji kun
-Tenjo Tenge
-Yu yu Hakusho
-Flames of Recca
-Ikkitousen
-Claymore

not main stream!!
most likely bakuman, death note, prince of tennis, school rumble, baka to test to shoukanjuu, gantz.
and recently i found very damn good manga 'ousama game' but after waited for 1 month there only one chapter.. when the next chapter will release.

Higurashi no Naku koro ni
Claymore

Your interest: Action / Comedy
Try Fairy Tail, Black Cat, Air Gear, Eyeshield 21, Sekirei, Deadman Wonderland, or Full Metal Alchemist

I'd also give Code Breakers a shot. I have to pick that one back up sometime.
