I stopped watching G4 since it just got crammed with re-runs of terrible shows like cops and cheaters, I never knew it when it was TechTV but early episodes of X-Play are a lot better then they are now. he jokes seem fresher and the set didn't look like it was designed by a four year old. It was more simpler back in the days but now it's over produced and terribly written.
That being said I think Adam Sessler is actually a pretty decent guy, he has his sessler's sopbox videos which I watch occasionally and every now and then a joke will slip out and it will be pretty funny, least a whole better then it is now.
Oh yeah, and Blair Herter is a twat.
