I was really upset when I heard they were bringing it back, but I actually enjoyed the sneak preview pretty well. Then again, maybe it was because my standards were already set so low.
I've got my doubts still, since really everything but the videos sucked after season 5 (and season 5 was already kind of weak), but maybe they'll fix the problems of the later seasons/movie (the main one being that they started writing FOR people like Beavis and Butthead instead of ABOUT them).
Seasons 2 and 3 were some of the best television ever, though, so you never know.
