O (2001)

"Few filmmakers are willing to examine teens and their problems in such a serious-minded, non-exploitative manner."

O Fantasma (2000)

"Despite a couple of memorable scenes, it's boring when it's not kinky."

Objectified (2009)

"It gets you thinking."

Observe and Report (2009)

"[Director Jody] Hill can create only one sort of protagonist, and half the time he's stuck in a gray area between satirizing the firearms-obsessed, multidirectionally offensive Ronnie and embracing him."

Ocean's Thirteen (2007)

"Thirteen is all about maintaining a barely perceptible smirk behind an impassive pose. The line between cool and cold is a thin one, however. Cool isn't the word for Thirteen; it's just smug."

October Sky (1999)

"One of the best in recent years!"

Off the Map (2005)

"As with many of the best non-conformist American indies and foreign films, it's taken much too long for Off the Map to achieve distribution, and it's been our loss."

Offside (2006)

"Jafar Panahi of Iran is one of his country's great filmmakers, and Offside is his best movie to date."

The Oh in Ohio (2006)

"A C- sex comedy with a near A-list cast -- at least in terms of talent -- The Oh in Ohio is one of those movies that promises much but doesn't deliver."

Old Joy (2006)

"Fresh as spring water and warm as sunlight, it steeps us in the beauties we will always miss, if we keep dividing the world into winners and losers."

Oldboy (2005)

"It's a movie of such jaw-dropping violence, wild improbability and dazzling style it overpowers all resistance."

The Omen (2006)

"Aside from a couple of brief, jolting dream sequences, The Omen plods along."

On Guard (1997)

"An awkward and indigestible movie."

Once (2007)

"For reasons they'll have to go to hell for someday, the Motion Picture Association of America ratings board gave Once an R, for a handful of swear words. Ignore that. And enjoy the film."

Once in the Life (2000)

"Fishburne is able to create such an effective balance between humor and anxiety that the movie survives its familiarities of character and language."

Once Upon a Time in the Midlands (2003)

"Meadows clearly has a flair for working with actors and for depicting the rough-and-tumble of ordinary provincial lives. If he could go just a bit deeper, the truly great Midlands movie just might surface."

One Day You'll Understand (2008)

"This is not a movie of big, dramatic revelations; in fact, the notionally elusive truth is pretty obvious from the movie's outset, which makes Victor's quest less about facts and more about principles."

One Missed Call (2008)

"The script appears to blatantly rip-off plot devices and story elements from The Ring, but screenwriter Andrew Klavan avoids plagiarism by tacking on an incomprehensible second ending where Ring would have left off."

One True Thing (1998)

"Meryl Streep is an actress of such transcendent skill and sympathy that she regularly elevates her material, taking it up several notches and giving us feelings, insights, feelings and textures the original writer may have just missed expressing."

Ong-Bak: The Thai Warrior (2005)

"Already a much-bootlegged, beloved martial arts film in Thailand, Ong-Bak delivers a new world action star in Jaa."

Only the Strong Survive (2003)

"Must be appreciated as an idiosyncratic chronicle as well as a collection of performances, some better than others."

On_Line (2002)

"If you like scenes of characters sticking hands down their pants, this is the film for you."

Open City (1945)

"Remains a film of electric drama and high emotion, as well as a major turning point in film history."

Open Range (2003)

"A strange mix of the grand and the hackneyed that it never really gets its bearings -- even though, at its best, it reminds us how grand, impure and potentially alive the Western genre can be."

Open Water (2004)

"A taut, 79-minute fright fest peppered with enough payoffs and glossed with a mournful philosophic overlay."
