The seventh Halloween film has been marketed as the last, which may actually turn out to be the case, as there’s an earnest and successful attempt to give the series a satisfying closure. Jamie Lee Curtiswho made her reputation on the first Halloween but dropped out of the series after the secondis now, 20 years later, teaching at an exclusive private school in northern California, raising a son as a single mother, and once again trying to fend off her murderously insane brother, who won’t stay dead. If you can accept the flouting of logic and credibility that usually goes with this kind of horror picture, this scary and suspenseful genre exercise, chock-full of false alarms and brutal shocks, really delivers, and Curtis approaches the assignment without a trace of condescension. Directed by Steve Miner from a script by Robert Zappia and others; with Michelle Williams, Josh Hartnett, LL Cool J, and Adam Arkin, and an amusing cameo by Curtis’s mother, Janet Leigh. (JR)
