1. A lot of its humour was roundly predictable. I think the moment that most exemplifies this is when Ralph Fiennes, in his first scene about half way (or perhaps even further in than that) through, angrily calls his wife an "inanimate object". But then, of course, the foul-mouthed hard-ass gangster lord (I assume) is going to softly apologise in the baldest terms possible. It just falls flat, and it does it too often- jokes like the American tourists rev up but suddenly conk out.
2. It went all weepy and emotional in so strong a way I'm surprised it didn't turn around and start calling itself gay, as seemed to be the prediliction of the film's central characters.
3. The well-built tension in the developing relationship between Ray (Colin Farrell) and Chloë (Clémence Poésy) came to a complete halt and she just became the crying girlfriend. The pregnant hotel owner was better characterized (and, let's be honest, more fun).
4. The dwarf (Peter Dinklage) cliche being upturned was done in such an obvious and boringly predictable way- particularly the way he was 'defeated'. Not good enough. Same goes for that debacle in the park with the guns.
5. The theatre was packed. Now, this wasn't in any way In Bruges fault, because, god knows, I'd never have thought so many elderly people would want to see a movie about Irish gangsters who swear incessantly going on a trip to Belgium. But being squeezed and forced to watch with about a fifth of the screen impaired greatly reducing my viewing pleasure, and if the film hadn't been so damned attractive to so many people- who were all where, exactly, when I went to see Dark Horse, or Away From Her?- then it wouldn't have happened and I'd have been able to watch in comfort. Which would, possibly, have helped me enjoy it more.
That said, I did like the narrative point on which the ending turned (no spoilers, people), and Farrell and especially Brendan Gleeson were very good. And the pregnant hotel owner was superb. C+
