I don't think they ran out of ideas. The thing that i hate about modern movies or the industry behind it is that they make a movie, let's take op's movie for example, which cost 80million to make, everything included. It made 100million dollars and is considered a failure. Any normal ass company is glad to pay their workers and make some money. Just imagine joe's plumber shop working for 9 month on a project that cost him 80k in labour and materials and he makes 100k, which means 20 k profits and he's like: oh no, what a shitshow, i didn't even make half a million.
