Future classic. Criminally under estimated today. Adult viewer. Bored with the adult cartoon that use sex/profinity/violence etc... because they can, and because it's an easy way to be "funny"?
The amazing world of Gumball (TAWOG) is , for the lack of a better word, Perfect.
It's playing with codes (obviously visually with the 2/3D mix, but also in term of scenarios).
Season 1 is a good starter but it starts to get really funny from season 2 and then improves.
The main reason it did reach a cult status yet is that it was broadcast on a kid network an US target, when it was a European project filled with adult (non sexual) references.
You can already see in reviews that some kids start to realize how many levels there were. My guess is that we need another 10 years (for them to have kids), and a wider distribution, for seeing a revival and reconsideration of this show.
In my case, I discovered it while watching kid programs to learn a language working abroad. Amongst all the programs from cartoons network, this one was the one only i continue watching once back home.
