These movies are based on the books.
I was slightly disappointed with this movie. I preferred the first one over the second, but the third one will be better.
If this movie had a maze like in the first Maze Runner, it would've been great because that was all what this movie was missing, but that wasn't in the book so anyways, I can't wait to see the third.
I give Maze Runner: The Scorch Trials an 8/10
