Boondock Saints is little more than an extended angry white male's violent fantasy of righteous retribution against a world that doesn't serve him any longer, and the doc shows clearly why that seed is in the film.

a quote I wrote down from the first time I watched the film:

Maniac Troy to God-Knows-Who on the Telephone: "And the way I think about it is, if I'm a fucking record company, I'm dealing with guys that live out of fucking garages that try and bang strippers to get fucking cheese sandwiches."

uh huh, Troy...
