Disappointing mystery

Rating: 8/10 (27 August 2017)

A boy wakes up in a cage being lifted up in a very odd place. As he doesn't remember anything, he finds out he's trapped with a couple of other guys which struggle to survive in a harsh environment, being surrounded by an enormous maze which is as lethal as it is big. Unlike the others, he's not willing to accommodate in that place, so he starts venturing in the maze, trying to figure out why they were sent there and search for a way out.
It seemed like a very interesting idea even from the trailer, but, as I was expecting, it proved to be quite a bad movie. That surreal place is being "populated" by some boys who are as intelligent as the concrete walls surrounding them. Instead of trying to find a way out, something any normal human would do, they waste their time mocking each other, fighting, or even bossing around. They are simply happy with their current life and are not willing to do anything to change it. The main character isn't much better either, many of his decisions being arguable, to say the least.
I gave it this rating for two main reasons. It has an interesting "arena", where the action takes place and, although it's mostly predictable, it brings a surprising and plausible conclusion, while leaving room for a sequel.
