Pewdiepie is overrated IMO, and let me explain why.
He is a bit of an arrogant ass toward everyone. I've seen some of his youtube comments but I don't feel like sifting through his fans right now. Also, there is the fake that he talks over parts of the game you need to listen to and then gets confused about it later, fakes being scared, etc.
He's in it for the money more than the games. I saw when he first started, and I liked him back then. But now its "LIKE" "SUBSCRIBE" "I'M THE BEST" etc.
Also I don't like a good portion of his fans, because some are almost bloodthirsty and quick to fight with anyone that dislikes him.
All-in-all, I watch other people now.
