Tau is a Netflix movie thriller set in an automated house. Julia (Maika Monroe) has been kidnapped by Alex (Ed Skrein) for his AI experiments. At first she's in a prison cell with two other subjects but manages to destroy it and almost escape. After that she's kept prisoner in the main house which is run by Tau (voice of Gary Oldman), an AI with limited real-world knowledge. Her only hope is to recruit Tau to her side before the two weeks are up and Alex lobotomizes her to retrieve the data he needs...

This is an entertaining movie with good production value. Special effects are well done. There's an interesting dynamic between the three main characters, though Alex is more of a minor character since he's often away at work. Ending is satisfying so overall a movie worth watching.
