ESCAPE ROOM is a generic kind of thriller that trades on the newfound popularity of thriller experiences, in which a group of friends willingly allow themselves to be locked in escape rooms before solving puzzles to facilitate their escape. A real-life CRYSTAL MAZE, if you will. I've seen a previous and very similar B-movie that wasn't very good, but this one is more mainstream and bigger budgeted, so there's more emphasis on effects. I found it quite similar to that '90s cult classic CUBE, although of course nowhere near as good, lacking as it does interesting characters and only tending to generate a minimum of suspense despite all the screaming and shouting.
