Out of curiosity (and the fact that they just added the show to Netflix streaming) I decided to check out a few episodes. It's a solid show, on par with any of the kid's shows of it's kind like Foster's Home for Imaginary Friends, Danny Phantom, etc... It's a great kids show that I can see why it has an adult appeal as well.
At least it made me laugh, which is more than I can say for most shows on TV.
