Nostalgia did work for Star Wars and Jurassic World - let's face it, neither of those movies were good.
However, both those had a long gap after the previous movies.
But I agree there could be a danger in relying on nostalgia for the X-Men as they seemed to do a lot of re-treading in Apocalypse and it didn't really work. It needs to be fresh and dynamic and approach the socio-political stuff in a more simple, bold fashion (like Civil War did with the idea of vigilante accountability).
nostaglia can work if people want to see films.with ghostbusters many didn't like the gimick.With star wars being first star wars film in 10 years and return of original cast that was the hook.now if you want to critize bryan singer for riping off or homaging X-Men and X2 with apocalypse J.J. Abrams is even more guilty of it with the force awakens.
I still haven't seen seen jurasic world so i don't know how they handled it.
with star trek now that disney is putting out a star wars film every year GA intrest in trek is dwlinding.If you look at box office mojo the adjusted for inflation domestic earning trek 1-4,VI,Generations,and first contact got bigger audence than beyond did.even motion picture and voyage home got bigger audence adjusted for inflation than Into darkness.nutrek has been declining with each film.It's similar to how the original trilogy had much better audence than First Class/Apocalypse.Apart from deadpool which is
higher than even adjusted last stand and X2 numbers only DOFP comes close.
fact remains new cast doesn't have appeal original cast did.let's remember even after last stand which at best can be described as mixed from audences and critics origins did better than eather first class or Apocalypse.
ignoring fact fox is limited because of problems with marvel/disney on how they can promate they could defently do better job with how they promate with what they do have.fox had better promatiol campagin with origins than they did with first class,the wolverine,and apocalypse.
if you look at rt audence score even though i have no love for last stand or origins they had a 62% and 59% liked.so not everybody hated those films.just like apocalypse has a 70% liked.though GA had more intrest in those films than apocalypse.
the biggest problem is return of original cast isn't fesable with jackman now done as wolverine.while odds are eventully wolverine will be recast i feel that is more likely to be done with younger cast.They might even try to get recqonable actor to try to create intrest.return of original cast got GA attention for DOFP.
DC films may eventully too like X-Men and Star Trek run into trouble.if films keep getting panned while they continue to be films audences rush to see.While audences liked all 3 DCeu better than critics will that hold out.
Fox,Kinberg,and Donner for next X-Men film may decide going into outer space and quickly recasting wolverine may be way to get people's attention.
