If someone wants to decide after reading the review then according to me it is a useless movie because when someone watches a movie then he tries to guess how someone would react in the scene according to the characters of the movie. Here in the couple the male character is shown strong and logical but his behaviour is not shown logical. If a male goes somewhere alone with a lady then he is not so off guard and when the matter comes to survival then he will not react the way it has been shown. It is an unknown place, there is no cell reception, neither of the couple has taken any kind of special training and on top of that the people there are also not behaving in a friendly manner, so no one would be as stupid as shown in the movie.
