In order of recommendation:

JARHEAD

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 LADYKILLERS

Just about every Coen brothers comedy is more enjoyable on a second or third (or fourth or fifth) viewing than it is on a first; once you adjust to Joel's and Ethan's Byzantine plotting, affected wordplay, and in-your-face staging - culminating in a style that can make their works seem, initially, show-offy and too quirky by half - the brothers' filmmaking exuberance eventually wears down your resistance, and their scripts feature some of the funniest non sequiturs you'll ever hear. (Nearly every movie fan I know can recite reams of dialogue from Raising Arizona and Fargo and O Brother, Where Art Thou?.) The Ladykillers, the Coens' adaptation of a 1955 Alec Guinness comedy, is mostly on the hit side of hit-or-miss, and I'm guessing that it, too, will eventually become a beloved treasure trove of quotable quotes, mostly because, on a first go-around, it takes diligence to decipher exactly what Tom Hanks is saying in it.
