What are your favorite/best/most unskippable TV intros?

With the advent of streaming and the ubiquitous "skip" button for the credits, it got me to thinking about the show intros I'd never "skip."

Actually doing a rewatch of Treme and I never skip the opening credits, at least for Season 1.

It's not "the greatest" but it does the job--nice tune, sets the stage, gives you a feel for the show.

A couple come to mind as GOAT:
1) Game of Thrones. Visually stunning, great score, and actually quite helpful in understanding the lay of the land. Loved that they would tweak it as the story unfolded (Winterfell burning, The Wall falling, etc).
2) Greatest American Hero. Tells the entire origin story and introduces you to the key characters. But the real star of the show is the song. I probably wouldn't enjoy an actual rewatch of this, but I damn sure can sit through the intro.

I actually skip the Sopranos intro, about half of the time. A great intro, but for me, not unskippable.

A lot of the modern intros (Westworld comes to mind)are visually interesting but I think they miss some of the building blocks of some of the GOATs.
