Well, while everyone is mentioning animes I actually like, I'm going to go ahead and put the hate on Naruto, the whole anime. It's only fair. I have my reasons. How do I put this?
For starters, nobody in this series is actually a ninja, or close enough to one. Not the stereotypical always-wear-black ninja, nor the real and actual peasant-who-uses-any-method-at-hand-while-under-the-radar ninja either. It's alot of shouting and jumping and increasingly-weird attack moves. Well, it IS anime, but let's not side-track ourselves too much. I like ninjas. If you're a Naruto not-a-ninja ninja, then I don't like you, QED.
But if you want a central focus to the anger, let's just go with the pinnacle character. Naruto has the show named after him and he's the main character, ergo this is all his fault. To me, he doesn't have a likeable personality or actual redeeming qualities. I'd call him the decoy protagonist, being something of a comic relief, except there's nobody suitable to take his place, because other characters are unlikeable in their OWN way.
Actually no, that's not true. There are SOME okay characters in my book, who actually seem alright. But there's no show if the rest of the cast is lacking. Basically, this could've been alot better if it were taken seriously. And I mean ACTUALLY seriously and not just with bi-polar angst and comic relief. If the creator of the show/manga had done this to be, say, the equivalent of Samurai Jack, it would've been GOOD.
