Put the kids to bed before you watch this one. Martin McDonagh tends to make darkly comic films. (His brother does much the same thing, but with a different balance between the darkness and comedy.) This, his first full-length film, is no exception. Brendan Gleeson and Colin Farrell are both In Bruges as the movie begins. They're not sure why, exactly, and neither are we. Someone's been killed, and now they're in Bruges.
