It's a quite classic horror-thriller movie that give tension from beginning until the end. The whole movie are so realistic and the accident are following each by each, which give the audience tension to find out what are happening next. The effects that showcase the mutant monsters and each of the scenes are fascinating. Personally think that the actors are so well brief and develops that giving so real response which adding points to this movie that giving all the audiences tension and enjoy the whole movie flow, wanting to continue find out what is going to happen next. I think I would definitely recommend this movie to everyone around me.
