O. Henry's Full House (1952)

"As with all such films, the interest level is entirely dependent on the individual stories -- and four of the five are very good indeed"

Obsessed (2009)

"I don't mind that Obsessed, is mindless, overheated, undercooked trash. I mind that it's boring mindless, overheated, undercooked trash."

Ocean's Thirteen (2007)

"In a summer where every intended blockbuster has so far been the third in a series it's a relief to note that the fourth third to come along is the best of the lot."

Of Mice and Men (1939)

"Inventive filming of the Steinbeck novel with a classic performance by Chaney"

The Ogre (1996)

"Haunting as the film is, it never feels quite cohesive."

The Old Dark House (1932)

"James Whale at his best. Not a false moment."

The Old Man and the Sea (1958)

"Tracy with a hokey accent floats in a studio tank for what seems like forever."

Oliver Twist (1948)

"The ultimate version of the Dickens novel."

Oliver! (1968)

"As big-budget adaptations Broadway shows go, this is one of the best."

The Omega Man (1971)

"So-so last man on earth flick that looks pretty quaint today."

The Omen (2006)

"The Xerox approach to the story causes it to add up to a huge 'So what?' by the film's end. "

On Her Majesty's Secret Service (1969)

"Best of the Bonds, thanks in no small part to Diana Rigg."

On the Beat (1962)

"Norman Wisdom was sort of England's Jerry Lewis. That says it all"

Once (2007)

"While Once doesn't really reinvent anything, it is a marvelous addition to the short list of genuinely good rock musicals."

Once Upon a Time in the Midlands (2003)

"Clever and generally successful attempt to present a British domestic drama with comedic overtones, all in the style of a Sergio Leone western."

One Flew Over the Cuckoo's Nest (1975)

"My basic quibble with the film is that it's part and parcel of the movies' unfortunate tendency to romanticize mental illness."

One Million B.C. (1940)

"Not great and it never was, but it's interesting."

One Missed Call (2008)

"It's always a relief to see Edward Burns in anything he didn't write or direct himself. But just realize: This is the first big release of 2008."

Only Angels Have Wings (1939)

"Possibly Hawks' best film -- a bold statement."

Only Two Can Play (1962)

"Splendid early Sellers vehicle with great performances across the board."

Open Range (2003)

"Costner has not only salvaged his own career with Open Range, but just may have done for the Western what Moulin Rouge! and Chicago did for the musical."

Open Water (2004)

"The Blair Shark Project is supposedly 'based on actual events' – which proves the Quentin Crisp dictum that 'even the worst movie is at least better than real life.'"

Opera (1991)

"Stylish, but inane and sadistic Argento thriller."

The Order (2003)

"Most bad horror movies at least offer the compensation of being unconsciously funny. The Order just makes you wish you were unconscious."

Orphan (2009)

"As the poster says, 'There's something wrong with Esther.' There certainly is -- she's trapped in this terminally dull and dimwitted movie."
