You take the good name of Star Trek out of your mouth.

SpongeBob, Simpsons, Family, American Dad

I remember watching Detective Conan in the Mandarin dub as a kid. Don't remember much of it now. I looked it up recently, and apparantly it has been running since the 1990s? Still ongoing... yea I don't trust anything that runs for that long, probably quality of the story went downhill if I had to guess. I have no idea how it's even possible to run a concept for 2 decades+ without it eventually getting repetative and boring. I was curious about what the ending would be, but it never ends.

Don't wanna watch something that goes on forever.

In addition to the three you outlined,

• Alien
• Predator
• Terminator
• Peter Pan
• Robin Hood
• DCeU

It will actually be a sad day when Fast and Furious eventually ends. No more Family jokes. No more wacky titles.

All of them.

My most radical opinion is that every story ever created should be made to end. And continuing any story past a well-made ending is a crime against storytelling.

We should have a law where sequelising a story that already reached a satisfying end incurs fines that quickly escalate into insane amounts of money. Redirect that dosh into funding actual original art.

Literally all long running franchises. There is a clear downward trajectory over the lifetime of franchises. It doesn’t have to start immediately, but goddamn if it’s not true for everything. Go out on top. Don’t go out floundering about the lower-middle (at best).

Doctor Who.

Spiderman.

IDK if it's still popular anymore or just tax write off slop, but definitely Scooby Doo.

I would have absolutely been in the minority back when it came out, but as someone who grew up watching it through reruns on Boomerang, I personally like some of HB's other attempts that didn't stick better.

As the lyrics to Running Under Water by Pain goes:

Me and my friends get no respect.

What does Scooby do that we neglect?

Currently the SC franchise is pretty much a walking corpse with the extremely formulaic plot of "the gang loves xyz and are going to see them/experience event" with little to zero prior showing that they care. Perfect example is literally the KISS crossover movie that came out maybe less than a decade ago. A basically dead band that's been out of the spotlight for a long time and a franchise that went creatively bankrupt decades ago are a perfect match for each other... Except they had to suddenly transform the gang into KISS fans for anything to make any sense.

Edit:

I think it's actually called Running Under Water and not Jabberjaw...

I think flipping the question creates more hot takes. Except for the series with self-contained increments, most "popular" long-running franchises just need to stop. Not necessarily close the franchise completely, but just let one thread end and create a new one.
