Michael Myers has been coming home for decades now, ever since he rampaged through the town of Haddonfield, Ill., in the 1978 horror masterpiece Halloween. The masked killer was supposed to be locked securely within a psychiatric hospital, but he escaped through many sequels and spin-offs. We’re supposed to forget all about those for the new Halloween, which is designed as a direct sequel to the original. (Then why is the new film titled simply Halloween? I worry about these things.) The creepy opening sequence depicts a Michael who’s been safely imprisoned for 40 years. Someone’s had the brilliant idea to transfer him to a new facility, which of course means putting him out into the world, which of course cannot be healthy for the world.
