5. Teresa Is A Traitor - Maze Runner: The Scorch Trials
The Twist: The survivors of the the maze escape the clutches of alcopop-producer-cum-evil-scientific-researchers WCKD and find their way to The Right Arm, a rebel group who hide out on one big location set. Things are all looking good until lone-girl Teresa reveals she's actually working with the bad guys and has called their troops to the good guys' location. Many people die and we get the fuel for another movie's worth of teenage angst. Why It's So Dumb: The Maze Runner topped this list last year for shamelessly trying to pretend its utter lack of closure was somehow answering key questions, so it can at least be said its sequel is slightly less dumb. Although not by much. Despite providing nuggets of context, The Scorch Trials didn't really explain anything (heck, I don't quite get what "Trials" the title's on about. And when the morality and goals of each party involved is so vague it's hard to tell which organisation is really right, the whole double-agent schtick is rather tired, nothing more than a highlight of how much this series relies on happenstance and narrative convenience. And it certainly doesn't help that Kaya Scodelario's role is made so slight that all she's does for the twenty minutes before this reveal is look uneasy at things. It's particularly pointless because you just know she's going to turn at the last minute in the next one (titled the spoilerific Death Cure) at some pivotal moment. Can this series just end now?
