In the Earth can feel dull at times and it's lack of answers is extremely unsatisfying but it has enough individual parts that work to make it a good and unique horror movie. Joel Fry, Reece Shearsmith and Ellora Torchia all give great performances. There are some extremely disturbing moments and oddly funny parts. Ben Wheatley's direction is really good even if some of his stylistic choices really don't work. The music by Clint Mansell is amazing.
