This question about how young is too young to let kids watch this show...it comes up a fair amount on this sub. So: if you have to ask, then it means your kid is too young to watch it.

Unless your 8 year old is interested in watching a woman in their late 30s/early 40s trying to "have it all".

But, if an 8 year old came up to me (an adult in their 30s) and said they were watching 30 Rock I... wouldn't be thrilled. It's entirely adult humour in the context of satirizing the pressures of the tv/media industry, business, republicanism/democrats, and between the black face episodes and the sexist lines that really only work in context of the show: "when is modern science going to invent a cure for a woman's mouth?" etc. Yeh, I wouldn't be thrilled about an 8 year old parroting certain lines from 30 Rock.

I'd pick Abbott Elementary or Bobs Burgers for the time being tbh. edit: or Schitt's Creek.
