There will be few who would argue that "In Bruges" is anything original as it is rather reminiscent of a Guy Ritchie gangster flick as the characters and plot tangle with each other in unexpected ways. The balance of humour and drama also matches Ritchie's output though due to heavy Irish accents, you sometimes struggle to hear all of the fabulously witty dialogue.
But "In Bruges" does offer some crucial differences, the biggest being Farrell who produces the goods in a way I never expected he could. He and Gleeson exchange some brilliant dialogue as they come to terms with past mistakes and choices. Fiennes is also very good as the urbane killer with a family life and a potty mouth. The other surprise is Bruges itself, looking every inch like the medieval dreamscape it feels like in the movie and provides not only a rich backdrop but also another character interacting with the actors.
