There are probably a couple of ways to look at this... iconic or execution. Iconic might cover shows like Fresh Prince, Simpsons or Star Trek. You know them and you remember them, but are they necessarily the best executed intros?

There is obviously an overlap between memorable and the quality of execution, if it is well executed then it is likely to stick with you. Execution describes that visceral reaction on first viewing. If I think about these kinds of intros, I'm going to go with Daredevil, M.A.S.H, True Detective and Westworld. My honourable mentions are Star Trek: Discovery and True Blood (yes, I know... but that title song is on point).
