How can I not let it get to me?

About a year ago, I watched an Internet celebrity insult one of of my favorite video game companies. He did so on the the account that they once made bad video games for awhile. He went as far as to tell the companies fanbase to kiss his @$$. The way he talked he talked about it, I feel he only made the review to uncover there dark past and ridicule them and there fanbase. (It may help that this company actually improved themselves and never did that again) But now I can't enjoy the games I used to because he's always lingering in the back of my mind. How do I shake him off? How do I not let what he said get to me?
