Short Version
Glass starts off pretty promising continuing both the stories of Split and Unbreakable but cracks start to show as the movie progresses with one particular character's behavior being very off. James McAvoy is the MVP once again with all the personalities of the horde but it's nice to see Bruce Willis back, Sam Jackson is pretty good once he finally shows up in the movie and my personal favorite would be David Dunn's son who is played by the same actor as in Unbreakable. The action is decent though depending if you care or notice how the budget may have limited the number of locations and when Bruce Willis is using a stunt double. Despite the movie being called Glass, Mr. Glass himself is largely absent till midway through the movie. The ending is understandable but is quite unsatisfying and the very end scene is a bit strange.
