Perhaps no one wants to write a beautiful, thoughtful, non-politically charged screenplay anymore. Or maybe doing so would itself be seen as a political statement?
You can literally watch movies all day every day and never watch a super-hero. It was never so easy to watch exactly what you want, when you want, spending so little. I don't get this kind of insatisfaction nowadays. Maybe the hidden premise is that what bothers you is not a lack of content you enjoy, but the fact that so many people love so much a thing that you consider inferior and a abject. To put it bluntly: that's cultural elitism.
It would be nice to see more new, original sci-fi and action. (but perhaps the other poster is on the money, and I am sure from a studio perspective it's easier to go with the tried and tested rather than out on a limb)
