In fact, I expected a little more from this film. A film in the bowels of a research laboratory made according to a real event, where the whole experiment gets out of control, is certainly a tempting topic. Unfortunately, the content of the film is no longer like that. The whole film came to me a bit sloppy, but it certainly didn't bore me. I like movies from the prison environment, but probably because it was de facto just a game, as some actors in the film said, it didn't bother me that much, but I still think that you will find this film for your fans. I definitely rate this film positively, even though I expected more from it
