Human psyche borehole

Rating: 10/10 (1 January 2015)

First of all - I absolutely love this movie. However I don't view it as a thriller as much as a deep psychological drama dealing with a wide range of issues faced in ANY human relationship. It's just dressed as a "mystery/thriller" which in its own way is a master pun as well.
I have heard many of my friends dismissing this movie as a little above average mystery thriller evaluating it along the lines of slow and predictable, yet usually entertaining. I think this is a huge misconception of this work of art, the thriller/mystery thing is just the outer layer, there are many more layers underneath in each and every scene and I'm very surprised people miss it. We are reminded about it at the very beginning by the first scene. The movie deals with the 3 simple questions posed at the opening scene. It actually is trying to unspool the brains of the main couple and get to the bottom of human relationships, not necessarily a marriage.
If you try and watch the movie through this prism, which is I think what the creators intended, you'll find a deep, thought provoking probe into the peculiar and intertwined web of little human actions of which human relations are made.
I don't want to go into any details here but I think everything (and I mean everything from camera angles through cats to the colors) has it's own purpose and meaning along the above mentioned lines.
Yes, human relationships, marriage, friendship, fleeting love affairs are in fact thrillers because we are always a mystery to each other. And that's what this movie is about.
p.s. and the workmanship is awesome - directing, music, acting ... everything fits, one of the rare cases where deep substance is met with perfect form.
