So this is a cartoon question! Decided to make one since this is also a cartoon society (despite the name). So, as the question says, what cartoon did you think would be stupid, but turned out to be fun to watch? It doesn't matter if it was in your childhood or not. It could even be a cartoon you recently saw!
For me, it would have to be 'Gravity Falls'. This was when I used to watch Disney Channel and not 'Comedy Central' all the time. When I first saw the very first commercial for 'Gravity Falls', I just thought "Oh great, another dumb cartoon being desplayed. First CN and now Disney? Gah". I just kept hating on the commercials because it didn't really give out any details to what it actually is, you know?
So once they finally displayed the first episode, I saw it, and I actually found it amusing. It's actually pretty good. I was quite suprised by the turn out, honestly.
All right. Your turn!
