You have to watch Split to understand Glass. This should of been named Split 2. As I was watching I kept thinking why would they have the same character with multiple personalities from another movie. The names of personalities were the exact same. I had to look through my movies to realize I wasnt bugging lol. It was just getting good when they got out of the crazy ward & then the movie ended. I was waiting to see what would of went down & how would the people react if the beast did make it to the building they planned on going to before they got out. Split was a whole lot better u got to see the beast at its best.
