I'll give Glass 7/10.
It doesn't have a lot of action scenes like Unbreakable and Split. If that's what you are expecting from this movie, then don't watch it. It'll disappoint you.
Some parts have action, some parts are a bit humorous and some are emotional with a lot of talking.
On the other side, If you like to find out some backstories and plot twists, then you'll appreciate the story.
It focuses more on Glass' ability and way of thinking on how to end their story, in which I think is amazing, but not that satisfying. (As it is the last part of trilogy.) Actors did well, but the movie could've became better.
