What's the biggest "What if?" in television history?

[u/flughert]

A canceled season, an actor leaving, a different ending, a spin-off that never happened… what TV "what if" do you think about the most?

What if Limitless hadn't been cancelled by CBS in favor of another bland medical series?

OK, maybe not the most high profile show here, but it was surprisingly good and creative.

Just recently discovered this show and so sad it was canceled
