Glass is the film that's to conclude a secretly planned trilogy following Unbreakable and Split, and if you're looking to see it as the superhero epic you expect, this isn't it. Because even in the age of this genre, this instead studies on the psychology of how comic book lore can relate to the real world; and for the most part, to me at least, Glass works.
We're brought back Bruce Willis' David Dunn, supposedly taking out crime around Philadelphia and formed a team-up with his son (played by returning actor Spencer Trent Clark). Only then Dunn is taken to a institution where Sarah Paulson brings him together with Samuel L. Jackson's Elijah Price and James McAvoy's horde of characters, and has to convince that their alter egos are in their head.
Now to M. Night Shyamalan's credit, he still brings a unique direction for this, such as color tone and different POV shots. McAvoy I think is great in this, the way he jumps from one personality to another is what stands out like he first did in Split, though this feels more like a sequel to that than Unbreakable. But while these are great characters, some would feel there could be more done with them, say like Anya Taylor Joy's Casey Cooke who, aside from having ties after the events from Split, she isn't given that much to do. And not to explain so much, but it does have the trademark Shyamalan twist, yet one that could leave the audience scratching their heads or find it anti-climatic.
Overall, it's ambitious in a way because while there isn't everything to love, you got to respect the expansion that's found in these thought-provoking stories. B- (Originally to be posted upon the film's release)
