In the late 70s, a toku series was created based on Spider-Man...not really much to do with the comics, but it's still incredibly bizarre, corny and funny. I love it, but then again, I'm a huge Sentai/Power Rangers fan. It has the huge fighting robo and everything.
Note - it's Japanese but has English subs. If you have half an hour to spare, it's worth checking out.
I too enjoy Naruto, and I hope it's dubbed well when whichever company eventually buys the rights to it. Also, I thought Fullmetal Alchemist was pretty good, even if it was hard to tell exactly what happened at the beginning there.
