Creep Box kept me engaged from the very first frame until the ending credits and that's what a well-directed, good quality movie is supposed to do. It's an unsettling and thought-provoking story that takes artificial intelligence and (to me), crosses over into an other-worldly /spiritual-dimension (people are speaking to simulated voices of deceased loved ones via an AI controlled box) which, at first, seems to be beneficial to humanity, you can observe how it might help people who are grieving, but as the film progresses, and you get deeper into the characters, their stories and motivations, and the danger of the device ending up in unethical/ profit-minded hands, it can all go horribly wrong. There's also the disturbing element of the device taking a life of its own and therefore, being uncontrollable by humans. It's a chilling thought.
There are other narratives that can easily emerge or evolve out of this film and take on a new direction while maintaining the core of its purpose/theme, which leads me to think it would make a great adaptation for a television series or at the least, a sequel that expands the narrative.
The music and cinematography blend extremely well together. It has an authentic quality that feels haunting, eerie and very tense (as I said, it kept me engaged and alert from beginning to end).
Geoffrey Cantor gives an excellent performance as do the other actors as well. They all match perfectly with the mood and atmosphere of this film. My only complaint is that I didn't want it to end.
