I can't comment on movies from Finnland in general or if there have been better ones in recent past than this one. But I can tell you, that this one is pretty damn good. And hopefully you're not offended by the "d"-word, because there's much worse coming your way in this movie. And while most of it could be viewed as borderline cliché and predictable as to were it is heading, the movie itself is able to not only get away with it, but be mesmerizing nonetheless.
It's the central performances (which includes the kid) and also the sensibility with which the movie is handled by everyone involved. Unfortunately stuff like this happens in real life too and it's not just fiction. Is there hope though? For the character(s) involved and for us in general?
