This whole article sounds like thoughtless fanboy rage that pretends to speak for everybody when in fact it doesn't. The prequels didn't ruin the original trilogy. If you don't like them, then don't watch them. It's as simple as that. Alien 3 doesn't ruin Aliens for me, because I don't watch it. I don't let the Jaws sequels ruin Jaws for me nor do I let the Matrix sequels ruin The Matrix.
Yet dude totally gushes over red letter media like he's some expert who figured the whole thing out. The reviews were funny, yes, and made some good points but I have a hard time having much respect for a reviewer who makes comments like "so you might like the movies, you know, if you're stupid."
