I've seen and I love "Roger and Me" and "Bowling for Columbine", but I didn't like Fahrenheit nearly as much. It seems to me very different from Mike Moore's older films, not nearly as funny/witty. He does, however, scare the sht outta you when he reveals really how influence the Saudi family has on/in this country.
If you like Bush as a president, this moview WILL PISS YOU OFF.
If you don't, you'll love it.
If you have no strong feeling for/against Bush, you'll get a great education.
