FMA:B is up there on “shows I wish I could forget just so I can watch it for the first time again”, and so much of it has is how many characters’ final moments (re)define them. Tossup for me between:
Yeah, I 100% get where you’re coming from. (And I agree with you; the Ori seasons weren’t the strongest of SG-1. Babylon 5 had a similar problem where they wrapped up the entire show’s myth arc, only to be told there’d be a sudden fifth season. It showed.)
I think for me a lot of it depends on whether they decide to “un-conclude” the existing story or branch it off in an entirely new direction. Like, looking to Stargate again, the Ori seasons struggled, but Atlantis was a great way to propagate the concept with a new cast, characters, and story.
I’m kind of ambiguous about the first point. I think you can expand on a tightly-written, concluded story… but not repeatedly. Furthermore, it requires you to - to some degree - shift the focus of the following stories. Continuing the meta-story is all and just fine, but the immediate story can’t be about the same theme/issue/encounter indefinitely.
It’s an episode almost or entirely composed of clips from previous episodes. Usually it has some sort of a framing device - for instance, in an adventure show, it might be the characters taking a ‘breather’ after a tough encounter and musing on how they got here. Or one character might confront another about a situation that’s been brewing, and the clip show is showing bits of that situation leading up to the confrontation.
On an aside, reception to clip shows is an interesting shift. For a long time, one or two were an accepted part of a long-running series - either because it let you make an episode on the cheap using recycled footage, or because in the pre-internet-streaming-on-demand world, it let audiences catch up on what had been happening in episodes they might have missed or seen months ago.
Nowadays, however, they’re almost universally viewed negatively, as their reason for existing is absent and they’re mostly taken as a sign of poor planning by the creators.
This. It says, “I acknowledge you are upset, and accept blame.”
It is unacceptable that Babylon 5 is not on this list. It was rare, at the time, for shows to have a multi-season story arc with character development planned from the start. JMS got his seasons, though, and used them beautifully. Every single episode, even those that don’t contribute to the main storyline advancing, either show a character developing or build the foundations for that development.
