this is a good film that can inspire the writing of other horror film stories, but it is very unfortunate when the main character of the three people who play to solve the solution in my opinion is very stupid for their age I will know what I have to do, the core problem in this film is thinking about the possibility of leaving or escaping from such a condition, it was then that the tense scene became less so that I was eager to berate the characters in the film.
