Most overrated…?
One Piece:
Sanji: One who simply picks up a graphic novel and skims a couple dozen pgs' or so won't even know WHY he's on the crew. His personality has cliche tendencies (Brooke being there only makes it worse); and in addition all his "Dramatic, serious, didactic" speeches and phrases are always forced. And no, smoking a joint and saying _shit–_literally–doesn't make you bad-ass.
Sir Crocodile: I just HAD to get on his nuts. Seriously, SandMan rip-off, just much more intelligent and charismatic. All he had to do in order to galvanize fanboys was butt-rape Luffy and mind-rape Vivi. I ask several people why they care about him and most are zombies who say "I thought Luffy vs. Croc round 3 waz t3h shiznat!1!". The funny thing is, my interest in One Piece was fading at that time, until Croc was introduced, then I was hooked. Reflecting on previous arcs I'd say Don Krieg and Foxy were the best villains.
Naruto:
Deidera: I think Hidan is the best Akatsuki. Deidera is "ok", the good-sport villain. But clay…? I don't get how that's supposed to be menacing. He's an S-class ninja. You know, his rise to power among the fanbase was just like Kaku. He is a lot like Kaku if you think about it; just has a shorter temper.
Neji: The guy is GARBAGE. All the potential in the world to become an "okay" character and a mediocre anti-hero at best, then they make him a pretty-boy goody-two shoes. Matter of fact, he wasn't very appealing before Sasuke retrieval.
Naruto himself: Getting stronger is not character-development. I'm sure someone else has elaborated on this matter. And how do you stay the same after 2 1/2 years…? How do you still consider someone your boy-friend after they try to kill you TWICE...? They need counseling.
Death Note:
L: He and Light are equals. Neither, to my knowledge (I am only on episode 21) have done anything to totally screw up the other's plans. I'm just wondering why he takes his sweet time.
Rurouni Kenshin:
Aoshi: I just don't like him, and very Sasukeish.
Yu Yu Hakusho:
All the characters except Kuwabara, maybe Chu.
I'm done for now, kinda sleepy.
