Boondock Saints was just a fun action movie, nothing more, the two of you are overrating the shit out of it, calling it "one of the greatest crime dramas ever" is bit of a stretch seeing as how it's not a crime drama at all, it's pure action, plain and simple, calling this movie a crime drama would be like calling Rambo a War drama, it's a action movie, and not even close to being a top 20 action movie of the past 15 yrs. let alone all time
That being said this is a franchise that will never see much mainstream success, and both BS2 and the upcoming BS3 should really be released straight to DVD & Blu-Ray, as that's how the majority of the fans that love this series end up seeing these movies anyway, nobody is going to the theater and dropping $10 to see these movies, but there is a demand for them on DVD
As far as the 3rd movie in this series goes, I sincerely hope they take their time writing it, and putting it together, the second one was more of an action/comedy than anything that all of a sudden decided to turn into a serious action movie at the end, and as a result it turned out to be a pretty shitty movie, making a sequel wasn't a bad idea, the fact that they waited a fucking decade to do it and then made it into a fucking joke however was
