The plot synopsis may not appear to offer much, but with McDonagh's track record on the stage and after scooping an Oscar for his short film Six Shooter, critics have been waiting for the release of the film with bated breath.

However, anyone expecting the Hollywood-style, high-octane, buddy movie that the film's trailer suggests is likely to be left a little disappointed.

Indeed, the first 20 minutes of the film meander along at a gentle pace as the pair explore the city with Gleeson joyously taking in the historical and cultural highlights, while the cantankerous Farrell sullenly tags along behind.

But despite the slow start, the sparkling dialogue and the pair's fractious relationship draws the audience into the movie and it soon becomes clear that In Bruges has an emotional depth one might not usually associate with this genre of film.

Farrell's performance as the guilt-ridden contract killer struggling to come to terms with his botched first job is flawless and Gleeson provides the perfect comic and emotional foil.

The mis-matched pair continually gripe at each other, but beneath the put downs there is a real tenderness and despite the random acts of violence which punctuate the film there are some touching moments.

The supporting cast of oddball characters and a brilliantly witty script create a sense of the absurd, which softens the blow of the brutal violence and helps the audience retain their sympathy for the two protagonists –– who on paper should be repulsive characters.

On the surface, In Bruges is a darkly comic romp featuring gunfights, fast-talking hitmen and a belligerent dwarf.

But at its core it is an intelligent, thought-provoking film which asks some pertinent questions about morality, loyalty and redemption.

Indeed, the film even explores the human condition as it shines a light on how we as people attempt to reconcile our flaws and mistakes with the morality which society imposes on us.

In Bruges is a fresh, classy film which is generally well put together –– but does feel a little clunky at times.

It raises some interesting questions without ever becoming dogmatic and its suitably ambiguous ending leaves the audience free to apply their own morality to the tale.

Whether it is a gun-toting, wise-cracking comic romp or intelligent, thought-provoking film noir you are after, In Bruges works on a number of levels and comes highly recommended.
