Well, Casshern is something original, why because it gets out of the " I'm a hero, I must save." (Bleach, Naruto, ...) He says "Hi", people die, we know shit about whats going, I think that alone is enough to have that series out in the spotlight.

And, by the way, I gave Ga rei Zero a shot, and well, it's awesome.

About replies; popular stuff isnt always great. Vampire knight deserves to be En Fuego ? No because even though emo clampish vampire stories are popular, they still are relative shit that won't compare to FLCL, Cowboy Bebop or anything thats absolutly genius.

TAMI - GRZ - Casshern. Those three things deserve some room, but come on, on what criteria are we gonna chose heh ?
TAMI is cool, funny guys with weirdos negating their powers.
GRZ is violent, multi POV story, blood, monster, fights, Yarh.
Casshern is a mindfuck, kick ass art design, top notch animation and screenplay and best sidechars.

Good luck with the choosing mods.
