This movie is best going into with as little fore knowledge as possible, because when someone tells you the genre of this movie, your preconceptions will almost certainly skew your expectations and experience.
This is not a typical movie in its genre. It's a lot smarter and more thought provoking. While there are thrills, and lots of suspense, it's done in a much better way that is of service to the characters and the story, creating a slow build of dread rather than cheap jump scares.
A very good movie with excellent acting and casting. Sennia Nanua, who plays Melanie also did a phenomenal job, Gemma Arterton was solid as the protective and caring teacher Helen Justineau. Glenn Close was also good as the Doctor prepared to do almost anything to find a cure for the disease.
The whole cast did a very good job and the music complimented rather than overpowered the movie.
Worth seeing and I have watched it more than once.
