Glass

Following the conclusion of Split, Glass finds Dunn pursuing Crumb's superhuman figure of The Beast in a series of escalating encounters, while the shadowy presence of Price emerges as an orchestrator who holds secrets critical to both men. - Sarah Paulson joins the film as a psychiatrist who describes herself as someone that specializes in “individuals who believe they are superheroes.” Present among her patients at a Philadelphia asylum are David Dunn, Elijah Price, aka Mr. Glass, and Kevin Wendell Crumb, aka The Horde.

This was literally a movie split in two halves.  The first half was awesome.  The story was coming together awesome and all the characters were being done justice by equally.  The pacing was great and James McAvoy was killing it just like he did in Split.  But then once the three main characters were together - the movie suddenly stopped moving forward and slowed down to a snail's pace.  It was literally like night and day and extremely disappointing after such a solid start.

I would still recommend people check this out if you are invested in the two movies coming together but just be sure to keep your expectations low because it definitely plays out pretty flat after a very promising start.
