Try as I might I cannot think of a simgle Norwegian film other than this one. I certainly have never watched one.
But despite some initial concerns I found it a pretty decent. My concerns were the comedy angle. I know very little about Norway when I compare it to the USA or the EU countries France, Germany, Italy, Spain, Holland, Belgium, etc or even the Commonwealth (ie cricket playing) countries Australia, South Africa, New Zealand and the various Carribean countries.
So in not having much in common culturally I thought that I might not get the jokes.
I did. I laughed in places, although its not a laugh a minute comedy. But it's well acted, well made, and well directed. It surprised me, and very pleasantly so I may add.
