This film is in many ways puerile. And it is over the top. And I did snigger and indeed laugh for the full 75 minutes. It's a great deal of fun and, despite the physical injuries the Dudesons regularly sustain, rather life-enhancing – they simply enjoy everything they do so much. It is an intensely physical film, and – for different reasons, unsuitable for male teenagers, the squeamish, or Britney Spears fans. (Presumably some people fall in all three categories.)

Although the dialogue is in English throughout and the film clearly hopes to find an American audience it is many ways quite a Finnish experience. The emphasis on landscapes and the changing seasons is part of that. So is the un-self-consciousness about bodily functions, taken perhaps to an extreme that an Anglo-Celtic audience may find surprising. I doubt that there are many cultures where people who perform stunts might be trainee teachers – but perhaps that's one of the lesser-known strengths of the Finnish education system?

Seven out of ten.

• Finnish premiere of the film was on a drive-in theater.
