Another generic cartoon that's only harmful to any small minds unluckily exposed to it. Socially awkward kid who spouts "fascinating" does not a scientist make. Horribly inept, painful to endure and even an episode around billy trying to steal a peer's property! Don't waste your money or your child's precious brain on this garbage.

I'm 15 years old and I watched it because it centered around a 14 year old kid who is oddly in 7th grade.(i'm a junior in highschool so they messed up the age demographic) I hate it because the main character acts the way I used to when I was eight so obviously I am not revisiting this series. I believe uncle grandpa is a better series even though it is nonsensical just because even though it's not great show I can see the effort the creators have put into making it.

It's too bad (Almost) everybody hates the show. Some people say it's awful, disgusting, or hideous, but I don't recommend them sayin' it. I'm fine with the first season. I don't mind, I like that show. It's cute like Victor & Valentino. Billy maybe is Uncle Grandpa's grandson. Zeke maybe is the son of Jon Arbuckle, stated in a movie I'm making. Marsha reminds me of a mix of Heathcliff and Smurfette.
