Fantastic Four was a great comic because of the writing.
And the only reason the MCU made Stark a genius in so many fields was because Disney only had his character at the time. Now that they have the full set of geniuses, they'll have to show the differences. The biggest brains in Marvel are Doom and Reed. And we should see that. There should be a collective nerdgasm when von Doom and Richards get all competitive by spouting space/time differential equations before von Doom becomes Dr Doom.
