You cannot see “glass” WITHOUT seeing “unbreakable(2000)” and Ofcourse “Split” it will not make sense to you. This is personally one of the most realistic superhero/villain movies out to date, that by the climax may make you actually question if you actually believe they exist. With unemaginable twists, it has surprising humor, horrifying, and sad moments. This (at times) somber, surprising thriller will keep you on your toes from start to finish if you pay attention drops gems from each previous movie you probably never noticed was intertwined with one another. The ending through my perception hints that there are more special people/hero/villains that exists outside of the main characters and will probably arrive in a spin off. If you’ve seen “unbreakable” and “split” already this is a MUST SEE.
