Venture Brothers
This last entire Venture Brothers season was a surprise to me because I had heard there was going to be no third season. Then, when these episodes aired, it took the entire concept to a new level. Stories were deeper, characters gained more sublety, and everything was funnier. The only downer was that us Cartoon Network customers who subscribed to the "HD" channel were punished by seeing the letterbox bars on the top and bottom while the image contained within was s-t-e-t-c-h-e-d and distorted. I even erased the last few episodes on my DVR because it was so hard to watch.
Now, with this Blu-Ray coming out, I can see the episodes as they were meant to be seen for the first time!
Also, the cover art, a tribute/parody of the 70's Atari 2600 cartridge boxes, is a hoot as well. Go Team Venture!
