The most recent James Bond movie No Time To Die (2021).
The plot was like a Bond fanfic. Okay, great you got to do all the stuff to Bond that wouldn't fly in previous runs:
spoiler
Bond finally spawns a kid after all that sex, actually loves some gal instead of using her, makes a mistake in judgement, and he maybe even dies, although no body is offered as proof.
Now what? That pretty much ends the franchise, because they've written themselves into a corner, and there's pretty much nowhere to go without a reboot.
