I am rather shocked by the negative feelings this movie generates. Sure there is plenty of violence and swearing, but it's all in good fun. All too often I am disappointed in movies that come from my home country but this one revived my faith in American cinema. Maybe the bad comments about this movie reflect a lack of understanding of American humor. However, bad reviews aside, The Boondock Saints is an American classic. I saw this movie in high school and it has been a favorite ever since. Everyone I know loves this movie and can quote all the best lines. The accents may be terrible (I can't really comment on the Irish accents) but overall the acting is good, especially Willem Dafoe as a sketchy FBI agent who eventually teams up with the brothers on their quest to purge the mean streets of Boston of crime. If you watch no other American action movie, watch the Boondock Saints.
