Alternate universes aren't complete fantasy. As improbably as they may be they are still possible. They're extrapolated from points of divergence. A decision gone a different way, a random factor falling askew, or in the rarest circumstances, an immutable law of physics differentiating in some fashion.

What point of divergence involves biological twins being born a generation apart? Additionally, certainly, they didn't declare Moira's age but there are SIXTY years between her first appearance and her second and she's barely aged. Additionally, the CIA does not allow non American citizens to join.

All this really becomes moot. Some things can be explained away and earn you a "No Prize", some things can't. The important thing is that Fox Films, simply didn't care. They were simply out to make a quick buck in the beginning since comic book movies were a means of making quick easy money without spending much. Expectations were low because none of the produces were producing quality films. Then Marvel Studios came along and crafted the Iron Man movie and changed everything, further solidifying the genre as a serious prospect.

What we should take away from this is that Fox is doing something surprising and noteworthy. As seen by the recent Spiderman movie, audiences now have higher expectations and the producers of such movies are putting more thought and efforts into their storylines. Sony consulted with Marvel and hired several of their writers for the new Spiderman movie. Fox, from the sounds of it, Fox is effecting a reboot of their franchise without invalidating everything that has gone before.
