yes, it's a murder and a 'whodunit' but it is so much more than that.
the characters are well directed and acted and feel totally believable. the detective work builds as the story unfolds and leaves you wanting to know what happens next.
it's not like any wam bam cop story from the US which may not be to everyone's taste. it's just far more realistic and solid with each character 3d. there's some humour and some sadness and lots of realism. the characters are real people, they don't have ridiculous hair, teeth and smiles or know things in a semi mystical way. they work it out and have hangovers and sometimes cry. You know, like real life.
I thoroughly recommend that you watch this.
