Given the quality of X-Men: First Class and X-Men: Days of Future Past, I want Fantastic Four (or should I say "Fant4stic"? Poor literacy is kewl, after all) to succeed, but I am not counting on it. While the comics Doctor Doom is a stupidly broken character, turning him into a hacker seems like a terrible idea. What is the worst he can do, hacking into Reed Richards' Facebook profile and sending an IM stating "I luv BBC " to Johnny Storm's profile? Probably not, but it is certainly a good idea for the upcoming Deadpool film. Fox, you need to hire me as a writer.
Anyway, the MCU is not afraid of mixing aliens, spies, robots and magic in their films and the results were good for them so far. Maybe Fox should have noticed that by now and risk portraying Doom as the technomage and sometimes-benevolent dictator he is? We would not even need a detailed origin story for that.

Sorry for this terrible joke, by the way.
