I watched it the first day of its release, and to be honest I enjoyed it, it was suspenseful, creepy, slow paced and eerie.
You can tell when a scary scene’s coming, which made it suck for me because the build ups weren’t great.
All I can say is that it was good but not as good as the other horror films that have been produced by Blumhouse.
This movie seems to suck for me, I don't know why but it's just random for a movie to have it where it's a haunted pool that makes people go into it and heals them only for then later that once you try and heal you gotta make a sacrifice.
