One PIECE!
IMO garbage, just garbage.
I watched the dub of one piece when it first came out for a season and it was pretty freakin' cool. They stopped showing it on my TV provider though so I never continued. I've heard a lot of mixed reviews, mostly about their sheer number of characters, but I know that at the begginning at least it was alright.
I really enjoyed Naruto, both the TV show and the graphic novels for quite a while. Also I know a lot of people that really enjoyed Bleach, surprised I haven't seen it on here already.
