It should be difficult to believe that, from such a small country by population like Iceland, produces this master piece. This shows perfectly well that it does not need a huge crew and writers when one team can be called more than talented. Simply clever from the start.
The characters are built so well that you either want to see them or not at all. The setting is absolutely amasing - nothing much but yet, everything.
One simply recognise these people involved, be them main characters or punters that you can only hope this will never see an American version. Do not touch this Hollywood, this is not for you - please let people look like people and feel like one.
