This French horror film certainly lives up to its name . This is a tension filled suspenseful extreme brutal slasher film. And I don’t mean a typical campy slasher . Throughout the first 80 minutes of this movie my only problem was the main character,Marie was unlikable, useless and incompetent. Then the last 10 minutes happened . This movie is a plane tgst had a good take off, a decent flight with some turbulence that crashed and burned when trying to land. I get what they were going for and it’s a great concept. But poorly executed. Even if buy what they are selling certain things don’t add up . I give it. 6.5/10 but damn it could have been a nine.
