Excellent beyond anything
Truthfully, I only have patience to watch excellent movies, and after a while on this site, I have found numerous movies that are worth mentioning, and I like to have the honour of including yours on my list. It is meaningful and it shows other people (who aren't Swedish) your valued culture, traditions and beliefs.
I agree with you: we should be able to hang our golden, shiny keys next to our doors and not worry a thing about it.
I enjoyed the movie even more when it's snowing outside (amazingly in May).
Also, it made more sense at the end for those who has the patience to watch it, as it reveals that Nim is in fact a pixie. Magical beings are to be respected, and this film showed it.
Finally, I think that if it was English audio, the portrayal of the theme would not be carried across as effectively as it had been in Swedish. Besides, foreign languages are cool XD
