With the exception of Space Ghost and ATHF, I think the Adult Swim shows have been inconsistent. Brak is really good half the time, and the other half of the time is just fucking awful. Sealab was great for the first 14 episodes, with only like one or two exceptions, but then it started shitting out some bad one's. The Legend of Baggy Pants was too terrible to be ignored.
And Birdman is NEVER good.
