They should have adapted Imaginauts and Unthinkable into one movie. Would have been a great first outting for the FF in the MCU. Imaginauts is a great first act to explain the team to a general audience. Then the rest of the movie is Unthinkable which would have shown the FF basically defeated by Doom and Doctor Strange has to bail them out. That way, Marvel wouldnt have to blow thier load on Galactus and we get a better set up for Doom
Whats the point of having 65 years of publishing history if you dont use these famous and treasured stories that are already written and storyboarded?
