Here, have an actual embed of the Youtube version, since it works now. Also since the above link is broken now.

Okay, I'm going to go ahead and spoil the #1 entry. I watched that whole thing knowing, just knowing, that the #1 entry couldn't possibly be anything other than Garbage Pail Kids. If that piece of shit movie hadn't been in the list, or even if it had been in the list but wasn't at the #1 spot, I would have been extremely, horribly disappointed.
Well, guess what? I was not disappointed. Garbage Pail Kids was in the #1 slot on this list. Doug Walker (not the Nostalgia Critic character... Doug Walker himself) rants about that horrid movie for over 15 minutes, which was only 10 minutes less than the actual NC review itself. It was one of the most glorious rants I've seen in quite a while, and I agreed with every single word, hand gesture, and facial expression of it (except, again, for the part where he said he loved the cards as a kid, which I most assuredly did not). I loved that Mr. Walker brought up Manos: The Hands of Fate, same as I did, and also compared it favorably to Garbage Pail Kids. The Garbage Pail Kids rant starts at around 36:30, if you only want to see that part of it (but I would recommend watching the whole thing, if you have an hour to spare).
