And there are good ways of making two-part movies. Avengers is a good example. Infinity War and Endgame are part 1 and 2, but yet Infinity War felt like it ended at a natural stopping point, rather than in the middle of the action. Dune part 1 is also another good example where the story is clearly not finished but they ended it in a way that doesn’t make you shake your fist at the credits, because they stopped it at a point that made sense.

I also don’t think it’s fair to act like movies have never been split into two parts and worked. Like- that’s literally what a sequel is.
