I still like Naruto because of the main character, Naruto. He is one of those rare protagonist that has to struggle against evil, train hard, lame, silly etc.
I am tired of those anime in which the whole plot revolves around the hero like he is the center of the universe. The other characters are just there as fodder to be saved by the awesome hero at the very last minute.
Regardless how strong/experienced the villain is, the hero will win in the end and often 1 versus 1 while his teammates are rendered useless and can only watch in awe.
