Well-photographed and well-acted movie with a good film score from a town I haven't yet been to. Not a good occasion to delve yourself into the beauty of the city - the dizzying atmosphere of Split on New Year's Eve it does make you feel, for as much as I can judge this, but given that it's nighttime, don't watch this movie just to make up for a missed chance to visit the town (visit the town instead, if possible). I wasn't disappointed at all by this lack of tourism promotion, though. The story really is the type that holds your interest very well, as pointed out before me, and it uses cleverly messed-up chronology to interweave lives in a city where foreigners might knock on your door with indecent requests and where drugs apparently are a problem - some minor or major side-branch of the big international drugs route to Western Europe leading through it, I suppose.
As to my vote: 7 out of 10 - well, it could have been 10 but for the ending. (Skip the rest of my comment if you're not interested in my otherwise non-spoiling remarks on it.) To paraphrase Hamlet, "Though this be a spoiled ending, yet there is method in't" - I can see the point made by the authors, and I wouldn't even say the ending's not fitting. If you have only seen this one instance of such an ending, it will work very well, I suppose. I have had the experience of liking a movie with this sort of ending, only to then run into comments here on IMDb telling me it's been seen before. But do watch the movie even in case you have an idea of what I'm talking about, I do recommend it.
