Yeah that's what I mean. I really like this show but the inconsistency in characters actions and personalities drives me nuts.
Like, here's an example. For 5 seasons I've watched this show slowly as it came out and Gumball and Penny's relationship is so built up, then you watch the ex. It's just a major kick in the pants for paying attention to the way the characters act. I've heard Ben say "Gumball isn't really supposed to have a personality, he is just a vessel for jokes" or something like that. Which is bullshit because we constantly hear characters talk about his personality based on past events.
Imo, the thing that bothers me isn't that the characters change personalities all the time it's that they keep the same personality for a while, and you think they are starting to develop and then the show just goes back to square one.
Fucking Ben, I love him for making this show but I hate him for doing this to the viewers who become attached to the characters.
