Saw this today. Very good movie. Not much i can say except that about the only thing that stops it being a 5/5 is that it seemed quite long- a few sections dragged just a tad. But well worth it.
If you want to see it, bear in mind there are some confrontingly violent scenes, and I'm not talking 'Hollywood war film' violent.
A very enjoyable whodunnit. PBJ will be able to figure it out from the trailers, for the rest of us, the joy is in the viewing
