Something can be lighthearted or action based and still be interesting film making in contrast to the paint by numbers MCU films and some others.
It's pure action, but Fury Road is an example of a simple action movie that had thought put into the editing, cinematography, etc. Barbie is light hearted but similarly had some ideas to play with.
Have movies typically planned and scheduled 10+ sequels/spinoffs in a shared universes prior to the MCU? I don't remember ever hearing that X1 is going to come out this year and Y1 the next with Z1 in the winter, etc etc over the course of 4-5 years.
Is that really similar to "pirate movies" or westerns or whatever from back in the day? When it comes to budgeting? Locking yourselves into set releases publicly, blocking theater schedules, etc?
