It seems like the Ghostbusters reboot, didnt really bring anything new to the table and thats why it failed. Jurassic World had the park actually open and Jumanji: Welcome to the Jungle let players into the game world. I dont think those crossovers will work; it seems like the concepts/novelties are what is attracting people rather than who are cast. They need to come up with something new if they reboot MIB, perhaps the agents go to an alien world to solve a case, and they are the actual 'aliens' who are being hunted down? I dunno. 21 Jump Street doesn't gel with that franchise.
