Again a Netflix original which is alright, but not really good.
After being kidnapped Julia finds herself in a cell which proves to be part of a high-tech house in which she is kept for testing. The Tau from the title is the AI system that runs the house for its master and simultaneously the system that needs to be improved by investigating the human brain.
In the beginning the film suggests becoming one of these torture horrors, but fortunately this is not the case. The director has some amusing findings, but also less so, regarding the high-tech house. Tau communicates with its master Alex, but only when Julia manages to communicate with it, a mildly interesting situation occurs in which Tau is a rather child-like AI system that likes music and poetry. Of course Julia is going to try to use that to get out of her situation.
Like I said, the film is alright, but not really good. The stages look good, the story is alright. I am going to have to find a way to find actually good films on Netflix…
