Red's actor doesn't fit the Takaharu character, you can see visually it pains him to act like those loud and yeller types.
It's not exactly that he doesn't fit Takaharu's character, it's just that for some freakin' reason, the directors(/producers?) try to make him yell like Gentarou did, but even worse... Aside from that, he seems to be doing decently for a new actor, not that it's hard to, anyway.
Yeah he is. I said that in the last episode thread, that Takaharu is just gonna run off fighting on his own, forgetting the god damn lesson he learned about teamwork. I bet they're gonna do it later on in the series again. Just bad writing.
It's actually logical... Just because someone learns a lesson, it doesn't mean they apply it to their lives. It's like finding out that too much sweet is bad for your teeth, but you still eat lots of it. You know what's right, but you can't really accept it into your life. In this case, we have 5 people trying to be the Last Ninja, and Takaharu seems the one who is more excited by it. That means he can't hold in his desire and just want to show he is the one deserving to have that title. So no matter how many "lessons" he is going to be "taught", he will still end up doing things in his own, but slowly start focusing on teamwork. It's a realistic writing.
