Too long, too dull, too derivative

Rating: 4/10 (28 August 2018)

Easily needed at 30-40 mins cut, no pacing, no tension, no sense of any menace or foreboding until the last 15mins.
The plot will seem very familiar if you have ever seen any of the satanic cult B-movies from the 1970's, I'm guessing the writer/director has.
The only plus point is the acting from Toni Collette & Gabriel Byrne, shame it's wasted in this film. The daughter is an interesting character but underused, the son on the other hand, is pretty bland.
At least it isn't simply a jumpscare fest, like so much modern horror. But why watch this when you could watch the far superior Rosemary's Baby instead?
