The film is Ratanaruang's seventh feature. A review in
Hollywood Reporter described the filming techniques as follows: "A large proportion of the film is shot with a handheld camera that skillfully simulates the viewpoint and sensory reactions of someone fumbling through the jungle, occasionally varied by some sweeping shots that take in the enormity of the area from above." Both this review and a review at Critikat, although positive, find the film would have gained by seeing its length reduced. Another commentator finds that the film "makes use of the forest spirits to portray how bad relationships can get" ==References==
