Im posting a redditor's pitch for an MCU Fantastic Four here because i thought it was perfect:
"How would you do an MCU Fantastic Four movie?

I think having them gain their powers by going to space makes too much sense at this point not to do. After Infinity War, the Earth's government will be desperate to find a way of defending itself from alien threats. Have Reed Richards invent the first warp drive, and the Four gain their abilities testing it.
Also, I would call their shuttle The Fantasy, so the media will be calling them The Fantastic Four before they even get their powers."
