Jake Gyllenhaal in JarheadJARHEAD

In movies, nothing is harder to define than tone, and the tone of Sam Mendes' Jarhead, based on Tony Swofford's Gulf War memoir, is so elusive that, hours after it ends, you might still not know what to make of it. In many ways, the movie is like a two-hour expansion of Full Metal Jacket's first 40 minutes, as the 20-year-old Swofford (Jake Gyllenhaal) and his fellow Marine recruits, pumped up to an almost insane degree, train for their mission in the unbearable desert heat and prepare for battle. In Mendes' film, however, there is no battle for his protagonists to respond to; the war ends while the Marines' bloodlust is still reaching a boil. The film is, in many ways, about the maddening banality of service, and it has resulted in an occasionally maddening movie, but its shifting tones and air of unpredictability make it impossible to shake off; at the finale, you might not know exactly what you've seen, but you certainly know you've seen something.

The Day After TomorrowTHE DAY AFTER TOMORROW

Despite all the hullabaloo about the film re-opening vociferous debate about global warming and its possible effects, Roland Emmerich's disaster saga The Day After Tomorrow winds up begging exactly one question: Just how much stupidity are mass audiences willing to accept in their summer blockbusters? In any disaster movie, rolling your eyes at the ridiculous onscreen events comes with the territory, but the enjoyable ones temper that reaction with speed and laughs; Emmerich's cheeky, entertaining Independence Day managed the feat of making the end of the world look like an absolute hoot, and that film, within its sci-fi format, is probably the most sheerly pleasurable disaster flick of the past 20 years.

Black Hawk DownBLACK HAWK DOWN

It has been widely reported that Ridley Scott's war drama Black Hawk Down, originally due later this year, had its release bumped up to qualify for year-end awards consideration and, in theory, serve as a balm for a country forever damaged by the tragic events of September 11. There's no reason to refute this, and there might even be a kind of self-serving nobility in Columbia Studios' decision, yet the film in question is a technically impressive atrocity, one that's perhaps even more heinous in light of last fall's terrorist attacks. Although based on true events and Mark Bowden's well-regarded book, Black Hawk Down is jingoistic, dramatically inert, and sometimes shockingly racist; expect nominations and awards to follow.

Jackie Chan in Rush Hour 2RUSH HOUR 2

I didn't care for the smash hit Rush Hour when it came out in 1998, and so the arrival of Rush Hour 2, needless to say, didn't fill me with excitement. But the prospect of seeing the great John Lone and Crouching Tiger, Hidden Dragon's Zhang Ziyi in supporting roles piqued my interest, and you never know when star Jackie Chan is going to pull off some miraculous stunts, so an open mind seemed appropriate.
