Avis Metacritic

Some kind of sweet, wacky masterpiece.

The movie bubbles with intellectual curiosity and narrative ambition.

Writer/director Tim Blake Nelson manages a finely tuned balance that is rare in cinema. Moving from the far reaches of comedy to the nether regions of drama, he never skips a beat or sets the pitch too high.

Part goofy drug comedy, part shocking bloodbath. It’s a riot of tones and genres, but unlike that other recent hybrid, "Pineapple Express," the parts add up to something larger.

The movie is a showcase for digital technology and for Norton’s virtuosity, but I wish it weren’t such a weightless shambles.

A mixed bag of often mismatched ideas.

His (Nelson) timing is off and his bullshit detector nonexistent. I don't much care for the Coens, but the sad truth is that their cynical nihilism is a lot less spurious than Nelson's earnest sentimentality.

Don’t be misled by the title Leaves of Grass. Do not expect literacy, either. This stoner comedy has nothing whatsoever to do with Walt Whitman or poetry of any kind.

It is so outrageous with its ethnic caricatures, hokey plot and twin-brother mix-ups that you know the whole thing is a lark.

A dumb comedy out to prove its genre-defying smarts--the title is both an onscreen-supported reference to Walt Whitman and a wacky-tobaccy allusion--Leaves of Grass is a mostly mirthless affair; not even the sight of Edward Norton portraying twins tickles as it should.
