I've seen most of it of it now and it's okay. All the videos except for a few new ones are on his website and the image quality isn't that great. You shouldn't get it for the Nostalgia Critic episodes. Because of copyrights he couldn't put any of the normal episodes on the disc. The ones that are on there are just the episodes that didn't include any movie footage in the first place, the one exception being Ramage (which is a new and hilarious video, one of his best imo).
The rest of the disc is just random Ask That Guy episodes and Bum Reviews. Honestly, unless you want to support the website (which is why I got the dvd), you're better off just checking them online.
And yes, there's already a thread:
