Slow? Yes.
Pretentious? Some will say so.
Worth watching? See the above.

A man is found dead at the bottom of a mountain; the lead detective is very thorough but also unhappily married, and the widower is a stunner he feels himself gradually falling for. As emotions begin to cloud his judgement and the case becomes much too personal, can the detective re-establish a professional distance... and does he want to?

This film reminded me of Hitchcock's stuff; I personally enjoyed it a great deal but I can understand why others wouldn't like it.
The acting is really good - I was totally enthralled by the characters - the script is definitely faultless for the most part and, where I really liked the way it was shot and cut together, there will be many who will say it's "arty" or "pretentious"... and I can see their point, but it's by no means one of those crappy style over substance type of films.

Recommended.
