O Brother, Where Art Thou? (2000)

"A flattening pile of artifice and conceit disguised as a road comedy."

Observe and Report (2009)

"Observe and Report feels more like a series of not-quite-successful skits thrown together than a movie with a script."

Ocean's Eleven (2001)

"There is considerable pleasure to be had watching a Hollywood formula crowd-pleaser, no matter how irreverent, that's been made with intelligence, wit and style."

Ocean's Twelve (2004)

"While the movie's lack of pretentiousness is refreshing, there's also a nagging sense of laziness to it."

Old School (2003)

"Inept Animal House knockoff."

Oliver Twist (2005)

"Oliver Twist is a lovely, tony picture, but it isn't exactly essential."

On the Line (2001)

"There is plenty that is dreadful about On the Line ... but the fact that the movie is not unbearable is reason for parents everywhere to heave a sigh of relief."

Once (2007)

"I can't imagine anyone seeing Once and not instantly falling in love with it."

Once Upon a Time in Mexico (2003)

"Even when Mexico isn't exactly making sense, it's still a blast to watch for its sheer chutzpah."

The One (2001)

"When one actor plays both hero and villain, the viewer knows that what is being shown is not an authentic dance."

One Night at McCool's (2001)

"It might have all seemed hip and edgy 10 years ago, but today, it just feels tired."

Only Human (2006)

"At times irrepressibly hilarious, Only Human milks every possibility of clash with dark humor."

Open Range (2003)

"There's a fine little western lurking inside Open Range: Too bad it gets drowned out by director Kevin Costner's pretentiousness."

Open Water (2004)

"Seen in a movie theater, preferably in the company of some shriek-prone friends, Open Water is nasty, discomfiting fun."

The Original Kings of Comedy (2000)

"The movie has the feel of a joyous blow-out party, and it's hard not to get swept up by its upbeat energy."

Osama (2003)

"Will touch everyone with its haunting sounds and images."

The Other Side of the Street (2005)

"A romantic and poignant twist on Alfred Hitchcock's Rear Window."

Our Song (2001)

"Anyone who understands the subtle shadings of friendship will appreciate Our Song's realistic slice of teen life."

Outlander (2009)

"There isn't a single scene in this story about a traveler from another planet who crash-lands on Earth during the Iron Age that doesn't remind you of another, better movie."

Outside Providence (1999)

"Aggressively bland coming-of-age story!"

Over the Hedge (2006)

"Spends none of the time that Michael Fry and T. Lewis' daily comic strip does staring at the stars or asking questions of the Tree That Knows Stuff, but the movie does offer an amusing animals'-eye-view on the absurdity of suburbia."
