“Cerebrum” (** out of four) was a pallid horror psychodrama about a young man (Tobi King Bakare) who awakens from a year-long coma and has to battle his controlling father (Steve Oram) once he finds that the reality he knew his whole life is a lie and that his father has kept him hidden from various truths he thought he knew. Both over and underdone as film is curiously bland and remote but becomes over-the-top and overly cerebal in its second half. Yet another film with the DNA of “The Shining” and “The Matrix” and many others but does not transcend its origins into anything fresh.
