It is one of those films which you have to say wow and speak all of that ***** guff about. It's not that great, but if you pick a few lines from a textbook and go on about it and how great it is it's meant to make you look really intelligent.
It's like foreign films, you just have to drop it into a conversation and hope this fact will impress people, despite the fact that, Norweigian or not, it is just a film.
But the fact that it is dead old is pretty cool, because it isn't as bad and primitive as you might imagine.
