if you go the Ultimates route, you won't get a well done version of Doom.Not reading through all these pages, but.....
I don't want the mutants in the MCU. Trying to insert them now would almost certainly just feel really weird and awkward. And I never really felt like the mutants made a lot of sense within the context of the wider MU in the first place. I mean, you're gonna be all racist about Gambit and the threat of mutants out-breeding homo sapiens, but Thor can sleep with entire villages' worth of women at a time, over the course of centuries, and *that's* fine? Even by the inherently flawed thinking of racists, that doesn't make sense.
And trying to say that mutants have been around the whole time in the MCU feels dishonest. Who'd really believe that? Maybe you make mutants a new development, a result of all the superhuman craziness that's happened since 2008. But if you do that you cut huge chunks of the X-Men mythos out, and the math still doesn't add up. If mutation began with the start of the MCU, those mutants wouldn't even be in high school yet.
So I say let the mutants keep their own universe. Just having people like Fiege Godfather the property will improve the quality of those movies, they dont need to be in the MCU to accomplish quality.
As for the FF.....they're easy to introduce. They won't be the First Family anymore, but its not like that ever really mattered.
Not an FF fan but if it means getting to see a well done version of Doom on screen, I am all for it.
