Over the Garden Wall is brilliant. Thank you Cartoon Network for allowing it to happen. Beautifully animated, wonderfully paced with just the right blend of humor and creepiness. Also - kudos to using the mini series format, I hope this is only a sign of things to come and more self contained short events are on the way. I'm tired of watching several seasons of a series that started strong end up wandering aimlessly with no clear endgame in sight.
The voice cast was exceptional, and the resolution handled perfectly. A big thanks to the other reviewer that gave the Cartoon Network programming history perspective above, explains a lot. Now if only CN could find a way to apologize for and right the wrongs done to all of the terrific DC nation series that were unceremoniously canceled.
