It reminded me of Cube/Escape Room movies in terms of the plot. It's not a bad movie, but it is the weakest of these kind of movies, the characters are not really interesting as soon as I've figured out the flow of the movie, I knew the ending is just going to build up for a sequel, I was hoping for a surprise in regards to that, but it is what it is.
