Obito has disappointed me immensely as an villian and even if you classify him as an antagonists he was supposed to be against Naruto as the protagonist in the end he was easily defeated. As an antagonist he didn't fulfill his role up until recently because he wasnt considered much of threat until after the pain arc. And if he believed in his truly believe in his goal he wouldn't been easily talked out of it. Compared to Orochimaru, Pain, Madura, and even Danzo his defeat is disappointing he went through all those power-ups, transformations, changes and drastic events just to get beaten by a simple conversation. I love Naruto, but this really disappointed me I was hoping for an epic death battle and on his death bed he would regret all he done, not now.
