Michael Wilmington, the Chicago Tribune:
Movie review, 'Bowling for Columbine'
By Michael Wilmington
Sometimes the best tool for probing a social malady is humor - which is exactly what Michael Moore does in "Bowling for Columbine."
At the last Cannes Film Festival, "Bowling for Columbine," a shattering and hilarious documentary about gun violence in America, received one of longest standing ovations in the fest's history - almost 20 minutes by my watch count - and that says something about both America and the ways we're perceived abroad.
The news isn't all bad. I don't think the hand Moore got was an outburst of anti-American sentiment. But it was obviously an expression of solidarity with his homespun radicalism, sardonic humor, underlying humanism and, most of all, with his unflinching portrayal of the epidemic of violence in our country - how bad it is and how we got there.
"If you want to tell people the truth," someone once said, "you better make them laugh or they'll kill you." "Bowling for Columbine," like all Moore's film and TV work since "Roger and Me," uses that strategy. It's a fiercely opinionated film. But it's also a fiercely funny one, and the humor is what makes it so effective.
Not here to convince anyone who's made up their mind that this is a bad movie but they are in a small minority.
