Very creepy, suspenseful and scary, with very good performances Olivia Hussey and the rest of the cast. It also featured a very dark and horrifying third act, that eventually led to an extremely dreadful ending.
It had some good scary moments, as well as good performances. The only bad thing was that the story was sometimes not very cohesive and all over the place. But at least it had some interesting twists. It might have been better if they went straight to the point and maybe elaborated more the story instead of leaving it until the end with an open conclusion.
