the amazing world of gumball is like 100x better
I can't stand that show. It seems just outright completely handicapped. I think I may have laughed at one episode (I did give it a fair chance watching probably around 15 episodes) and that was the episode where their dad was on drugs.
The jokes on that show are insanely dry/the type of funny that an 8 year old likes. (which is fine since it's aimed at children anyhow)
I like adventure time though, it's funny enough to keep watching, some episodes are a miss but more are hits. The magic man episodes are hilarious.
