The Maze Runner (out Sep 18) can be enjoyed for two reasons. Firstly, it's a cool, intriguing mystery about some teenagers trapped in a giant maze. Who built it? Why are they there? Secondly, there's an interesting dynamic between the characters. Not all get along and it's very Lord Of The Flies-esque. Shot for just $30m, this film held my attention all the way through. Grade: A-.
