Review by SnoopyStyle

A prank at the all-girls boarding school Fairfield Academy leads to the death of a student named Kerrie. The prank seems to have brought out a real supernatural spirit. The death is assumed to be a suicide. New student Camille Meadows (Suki Waterhouse) arrives to take over Kerrie's room. She gets into a fight with the clic of girls involved with the prank and they all get detention. While in detention, they decide to perform a seance to contact Kerrie.

It's all very average and middling starting with lead actress Suki Waterhouse. The story, the location, and the filmmaking are all middling. It's not actually scary although it's a little spooky. The twist is not shocking as much as it's a relief that it makes sense. The mystery is the same. I'm just glad that it's not completely stupid but the reveal is a long information dump.
