Show / Cartoon Openings & Intros

[sdp]

As we're all aware intros and openings have been dead for quite a few years at least in western shows. The trend seemed to have started in the mid-00s when most intros/openings were shortened to 30 seconds to make room for more commercials but because of rise of binge watching and people skipping intros they've become irrelevant. If we get a short theme with the title that lasts 5 seconds is the most we seem to get nowadays. Even the simpsons the intro got shortened and then now it seems they only show the logo and skip everything else.

I miss them, but were they actually any good, did they really serve any real purpose? Or do we feel nostalgic for them in a stockholm syndrome kind of way since we had no choice as kids but to watch them and force to like them?

This isn't a "post your favorite openings/intros" thread. As a kid I loved intros that had all original animation and hated the lazy ones that reycled footage from the show. I have nostalgia for many though I don't even know if most of them really are really that great Western intros never have the love/care that anime openings have for example.
