There’s still lots of other studios and new players getting in all the time. My main point is that Fox aren’t exactly setting the world on fire based on their track record (each of the franchises I mentioned are their only true hits and half of them are a disaster). Disney can be a huge steroid shot. We might miss 1 or 2 Fox type movies each year (Kingsman wouldn’t happen under Disney) but I expect other studios to step in with those kinds of properties. People eat things other than McDonalds.
Restart clearly for me. And I’d move on from Jackson. He was great but we’ve seen his Wolverine in lots of movies. Plus he’s about to hit 50. Give Wolverine to some guy around 30 and get another dozen years of great character moments.
Introducing the FF into this universe seems easy - Reed and family disappeared a decade ago and no-one talks about them, a scientific experiment gone wrong, until they appear in Times Square warning of a God coming to eat the planet.
Introducing the X men is harder. It’s a clumsy narrative to have mutants suddenly be a thing when there’s been no mention before. Dr Strange just became the Sorcerer Supreme, magic was hidden from the world beforehand. Are all mutant hiding? Does no-one know what Xavier can do? Was there no such thing as Magneto in the MCU history? I’m almost tempted to want to keep the X Men separate, but fans won’t allow that to happen. So my guess is they’ll go the Ultimate X men route and have all mutants essentially be brand new, maybe a consequence of the Infinity War, with only a couple of guys having these powers for years and never revealing them.
