As an adult watching a kids show, I have to say: This is some seriously funny shit! Of course, if you have kids, they will love the characters and action... but as an adult you will end up looking forward to the next episode. Very upbeat. The voice actors are first rate (take a look up there to see who is in it). The one bit about knock-knock jokes actually had me laughing out loud. Face it: sometimes it's great to just hear a good joke.
This is exactly what to expect from the director of "St-Maud". A history of love and violence with a lot of "noir" and "fantasy". Excellent acting and great score by Clint Mansell.
