I couldn't agree more with that review of The Regular Show. It's just... bland. Not even funny at all, and I can't stand the characters. There's better entertainment on Cartoon Network(although with Generator Rex on hiatus and Sym-bionic Titan cancelled, you'd be hard pressed to find what it is if it's NOT related to Star Wars or Adventure Time).
Gumball is mildly passable. Chowder did the whacked out comedy in a surreal world thing MUCH better.
