I mean it's no worse than something like Dredd, which has a thread full of people calling it "fantastic" and "great".
on this, I can somewhat agree
I think I give too much credence on the setting of any movie. You give me a movie with voice-activated guns, I give you some slack
you give me a movie set in present day with shotguns, I feel there's a different set of parameters you need to adhere to
FWIW, I think Dredd was much better than Boondock, yet neither are re-watchable
