Recall the movie Aliens, where the action starts around an hour into the movie. In contrast, consider one of the latter Star Trek movies, where the action starts within the first five minutes.
In the past, directors had more control over their works, the target was a domestic market, ticket prices were probably relatively cheaper, there were few blockbusters released per year, and development time was usually long (sometimes, three years between a movie and any sequel).
Now, producers have to intrude more because they have to spend incredible amounts of money (sometimes, with marketing costs almost the same as production budget), with an international market to consider (which means making sure that the story can be understood across various language groups), lots of spectacle needed (which helps using CGI) and a long movie most of the time (to justify ticket prices), usually hitting a PG sweet spot, and a make-or-break attitude coupled with the drive to squeeze out as much as one can from a franchise plus keep producing as many works as possible to keep business cycles running (hence, remakes, reboots, rehashes, re-imaginations, retcons, sequels, prequels, spinoffs, etc.), especially when viewers have to spend much higher amounts of money to choose among so many movies while considering just waiting a few months before the movie's made available via streaming or even in a bargain bin.
That's also why many new movies look alike.
And similar has been taking place for television, music, video games, etc.
