I think the problem that most of you have is that even if just unconsciously, you expect his reviews to be serious.
His reviews aren't serious. The games he reviews are about 20 to 30 years old. So it doesn't really matter what he says because nobody is going to buy these games or even has chances of being able to buy them. I mean, his first review WAS just a joke-thing he made for his friends.
I admit though, sometimes, especially recently, he just started to swear randomly and his constant "I'd rather drink this out of that anus"-lines have become really annoying, but all in all, I still enjoy his little "show". It's really not THAT bad.
Most of his fans are idiots though. Such is life. Things get famous, morons start loving it, and instantly it's cool to hate it. Might not be the exact case with this here since even I agree with the flaws that you people stated, but I see some similarities.
