The only thing that made this watchable was Suki Waterhouse. It's an average teen mystery of the horror genre. I wasn't bored, it was a watchable time passer for a Sunday night. Held my attention. I did find some of it predictable, I predicted the reveal, maybe others won't. Was it scary? No. Was it intriguing? Yes.
If you like this type of thing and have nothing else to watch, stick it on as an okay time passer.
