We, as fans, will probably like it, because lots of people were waiting for a more action-heavy X-movie by Singer.
I think the critics could see it as 'another generic superhero movie'. Whether it will get good reviews probably depends on how much XA can add to the genre.
Pro:
- McAvoy and Fassbender gave nuanced and emotional performances in FC and DOFP.
- The 80s, but it depends how prominent the time setting will be.
- The diversity of the cast.
- Young potentials like Sheridan, Turner and Smit-Mcphee, who could become big a la Lawrence after FC.
- Isaac is the wildcard. As an actor, he's well loved and very popular at the moment.
Con:
- Despite a good performance, Isaac's Apocalypse could very well be so bombastic, so powerful and so dramatic as a character, critics will throw him on the cliche unnuanced villain pile.
- Worldwide destruction is not exactly undiscovered territory and the story could suffer from sameness, since we all ready got 'end of the world'-like scenario's in MOS, Avengers, AOU, BvS,... . The story really needs to accentuate its underlying themes and threads, so the action is justified and perfectly dosed.
