Something like Doctor Who, where there isn't an overarching storyline, can run forever, and I'm fine with it.
But a show where there *is* a storyline? That needs to stop, and I'd prefer it to stop as early as possible.
While I later found out the author is a jerk, one of my favourite webcomics is one that went for 150 pages and then finished. It could have gone forever. But instead, it was very satisfyingly concluded, long before it overstayed its welcome.
