I've rated movies on imdb.com for a long-time, but never reviewed a film.
Sacrifice is one of the worst movies I have ever seen and I've seen a lot. The film is a mess from start to finish and has very few redeeming features.
The plot is incoherent and you could drive a bus through some of the plot holes. They set up several strands that were semi-interesting, but the film ends without resolving any of these, and I mean any of these. I had to check whether this was a TV show and what I had seen was the pilot, but no this was a self-contained film. Some of the motivations of the characters make no sense, and there is a big reveal towards the end, but even this is so badly mishandled and there is no conclusion to this.
I would strongly recommend you avoid and don't watch this.
