I don't usually review reviewers. It tends to get a bit too recursive. However, now and again there comes a special voice in the wilderness. I have praised the Nostalgia Critic, and now I give you Otaku Assemble.
The thing I love about this guy is his enthusiasm. He really gets into what he is reviewing. He hates the villains with a passion and nearly high fives the heroes when they do something particularly bad ass. You can't help but get caught up in his passion. Start with his reviews of "Game of Thrones," as I think they are particularly funny.
You can find him here.
