I was never a fan of the X-men. The only movies from that universe that I really liked are the 2 Deadpool movies (Yes, he's from X-men), and LOGAN, which is just ... wow.. a movie by itself.
The latest X-men movie is the last one by
20th Century Fox because after this, the rights belong to Marvel and Disney. That means that legally, they can now bring characters from the X-men comics into the MCU.
I'm sure some fans are drooling for that, but for me personally I hope they don't. As much as I like Deadpool, seeing him in a Guardians of the Galaxy movie would not thrill me.
I don't know if the Comic book movie is dead, but I'd say it needs a break after Avengers: Endgame. But then again, another Spiderman comes out next month, and "AssGuardians of the Galaxy"(Lol!) is in the works, as is Doctor Strange 2, Wonder Woman 1986, etc etc. It seems the creative minds behind these movies aren't done yet.
