I personally really enjoy Adventures of Gumball.
Once you realize that the show is about life in Middle School you really understand why the show is so crazy.
Cause all my memory from Middle school reminds me that people were pretty irrational then, which leads to crazy behavoir. I do agree it take a while to get into the show as it does have 13 year old humor, but consideirng that is the audience they are going for it works perfectly.
As I begin to reminice about that age, I do notice that I had a lot of the same experinces he does in the show, not quite to the blown out poportions and not quite as crazy. But the core life lessons, and how he treats people I have done at least once in my life.
Like in the Episode: The Dream, is about how Gumball has a dream where his friend/brother kisses his girl friend and he cannot get over it.
At that age I had very irrational dreams like that, and it did effect how I treated other people as I no longer had a shadow of a doubt.
I think the big issue is that the are aiming for an audince that is 9-14, and their world is much stranger and different than adults. Even my parrents cringed when I selected what cartoons I wanted to watch in the 90s. I think it happens every generational gap.
If we are removing every show that has a family, you would eliminate almost all TV shows.
I understand the perspective you are coming from, but honestly Gumball is a great show. I would be sad if the stopped making it as the last 10 episodes have been top notch.
