Fantastic Four: 10 Things The MCU Must Deliver

For the love of God Marvel, do not make the new Fantastic Four a group of teenagers. It's a concept which crashed and burned in the Ultimate line of comic books, and one Josh Trank attempted to pull off on the big screen with his critically panned 2015 reboot.

In a way, the idea that the heroes are part of some sort of government funded think tank is a clever one, but it also robs the team of much of what makes them special (they're a family of "Imaginauts" who embark on missions together without any sort of interference). Of course, just like using an adult Spider-Man might have been problematic, how do you explain where this team has been hiding?

Well, they actually got their powers as adults - Reed Richards even had his white hair - and their absence could be explained by them getting their powers after Avengers: Infinity War or during Avengers: Endgame. Alternatively, they may have spent years in a different part of the universe!

Simply put, there are ways around it which definitely don't require a teenage team of superheroes.
