It's beautifully told story about dark side of our life, about love (or lack of it) and life (or lack of it). But not only, it will give you some food for thought in many many areas. It's not ready-made fast food, you have to think along and thinking is not always easy thing to do. Being a parent will probably help you a bit. This film will tell you a lot if you care to listen.
There is something this film does not tell you but it may be good to know - Estonia is one of the top countries in male suicides per capita and by large talking about suicide is considered to be taboo. That may explain negative attacks toward film and director in reviews.
Technically it's not perfect movie, but it's good enough not to notice it while watching. Given virtually non-exciting budget - team has done excellent job there.
Give it a try, it's not for everyone, but it's well worth seeing.
