The Boondock Saints is actually one of my favorite movies as well. I got extremely excited when I read your post because not many people have seen that movie which makes me sad because it is so hilarious. I love how they wore rosaries and thought it was their calling from God to kill all those bad guys. I don't think the sequel was that bad I was kind of mad that they replaced Smecker though. I love how the movie had a mixture of genres. There was action, comedy, and violence. I don't think there was ever a dull moment in that movie. The protagonists of course were the brothers and Agent Smecker was the antagonist. The conflict was that Smecker was going after the people the killers and was getting really close to finding out who they were.
