Definitely one of the better Shudder originals to have come out. It was a pretty freaky movie with a few disturbing scenes.
Satanist films are always pretty messed up. I mean, they were trying to do a good thing by brining their grandson back to life by using the dark arts. I guess people will go through anything it takes to bring back a loved one.
By the end, all this crazy demon stuff happens and the film concludes with an ending that is open for interpretation. I'm a simple guy so I like simple endings. I guess it's off to YT to watch some ending explained vids.
