Frances McDormand and Charlize Theron in North CountryNORTH COUNTRY

At a serious, well-intentioned "issue movie," you will periodically hear from a sect of the audience whom I refer to as the tsk-ers. Tsk-ers are especially vocal at works in which the leading figure - always righteous and noble, and prone to suffering in silence - finds him- or (generally) herself experiencing painful hardships in the cause of Doing the Right Thing, while their families, friends, and the world at large all turn against them.

Recently, some friends introduced me to the considerable pleasures of Freaks & Geeks on DVD, and I understood why the show barely lasted a season; it was a nearly pitch-perfect rendering of high school's everyday horrors and comic humiliations, and what mass audience, hoping for mindless entertainment, wants to subject themselves to that? And just like that sublime TV series, Mean Girls, the new teen comedy directed by Mark Waters and written by Tina Fey, is so wickedly sharp and achingly funny that its target audience probably won't know what to make of it.(At the screening I attended, everyone laughed like hell at the overt physical comedy, but the movie's most hilarious dialogue fell on deaf ears.)

Robert Redford and Brad Pitt in Spy GameSPY GAME

Tony Scott's Spy Game opens with one of those enjoyably implausible preludes we're used to seeing in the James Bond series: It's 1991, and American CIA agent Tom Bishop (Brad Pitt) is attempting to free a female captive (Catherine McCormack) from a Chinese prison. How will he accomplish this task? Why, by masquerading as a doctor called in to give vaccinations to the inmates, feigning fatal electrocution after touching a wired prison fence - which results in the momentary shut-down of the prison's electrical power, including its surveillance cameras - lying "dead" on a hospital gurney, fleeing the scene when no one's looking, scrambling down ratty corridors in search of the captive, bribing a mentally defunct witness with a piece of gum, and accompanying the prisoner back to the "dead" man's gurney, where prison guards will unknowingly escort the duo to an ambulance and then to freedom. And what trips up the plan? The gum.
