I watched this movie just recently .. and i was captivated. It is one of those movies that feels very condensed to one location. So the location needs to be exciting and varied enough.

In terms of plot - it is the "usual" clue/murder mystery. In terms of storytelling, there is a lot of flashback (some right, some wrong) and the accompanying interrogation.

The characters are for the very most part interesting and very well acted (although they do portray strong character stereotypes - so not too subtle) - but the chemistry and likability/or dis-likability .. is that a word? .. is quite well done.

While the plot is straight forward, it quickly gets more complex - morally as well as technically .. but never so convoluted that one is not able to follow it anymore.

conclusion: i can fully recommend this movie. Due to the nature of it (being a murder mystery) .. it is not suited for re-watching though.
