Also I watched 4 of the movies. About 15 episodes of the show. They make Ash a lot smarter, not much, but a bit more in the movies then the show. Yes that is the common anime protagonist flaw is being super tough and strong chosen one who is dumb. My character is not dumb, just of average intelligence.
But you're right about the expression thing. I agree with you there. There is only one anime I watch in which a main character is my favorite character. Not number 1 but number 3. So your theory still stands. Oh and if you're wondering what the show is. It's Naruto Shippuden. My fav list in order is Kakashi, Shikamaru, Naruto. Then for female leads is Hinata, Tsunade, I forget what her name is but the blond girl with pigtails who wields the big fan and fights with Gaarra. Also think she wants to bang Shikamaru.
