I don't think Spriggan was stupid, its just that the plot was very convoluted. A good bloody anime with Violence? I would suggest Grappler Baki or New Fist Of The North Star. Can't go wrong with a guy poking you in the head with his finger and your brain explodes.
Also today marks the first time I watched Naruto the anime. Now I usually don't watch much anime cause I'm a Harcore Manga Otaku, but I sat and watched the first season of Naruto. All I can say is WOW. The anime seriously gives the manga a run for its money. So here's my question of the day:
What anime have you seen that made you say,"Wow, this is just as good or even better than the actual manga?"
My answer would have to be Naruto, Onegai Teacher, FLCL, and Ai Yori Aoshi.
