I watched this with my girlfriend, who said it was one of the best love stories she had ever seen - I tend to agree. I am not usually a fan of love stories, preferring a good zombie flick, but this one transcended the genre by showing emotion and motivation of the characters in such an interesting way that you couldn't help but sympathize with them.
I confess that my motivations for watching it were rather base; I heard that it was about teenage Swedish lesbians, and thought that was a subject I would certainly like to explore in more depth. On the one hand, there are none of the explicit scenes I was hoping for; on the other hand, I got into the movie so much I didn't miss them.
Fans of love stories, teenage angst, girl power and anything related will definitely like this movie. Other people will like it too, you'll just have to talk them into watching it. It would certainly make a good date movie, or just one to provoke discussion and romance.
