I don't know how was the promo campaign run in the other parts of the world, but here in the Czech republic it was a bit too confusing. One awaited another crazy comedy like American Pie, where the only goal of the male teenage characters was to score (that means to have sex with a girl:-) The fact is that the movie is about having first sex, but it is also about friendship, growing up, communication with parents. It is not a must-laugh-very-loud comedy. The movie tries to look more under the surface. You will definitely laugh, but not loud, it will be that bittersweet kind of inner laugh (if you know what I mean).
The movie is a good compromise between a not very demanding teenage comedy and a deeper look into a soul of a teenager. Not only teenagers but even the older ones (like me :-( )can watch it. While watching, you will both relax and think a bit at the same time. I can easily imagine the scenario being spoiled by Hollywood filmmakers. What makes the movie well balanced (yet another time!!) is also the fact that it is a Scandinavian movie.
I personally love this kind of movies. So if you like movies like Finnish "Pearls and Pigs" or Swedish "Fucking Amal" you should definitely see this one. If you match the movie with the right genre, you can't give less than 9 stars.
