I don't have much to add, I would have to pretty much agree with what has been said in the earlier comments. This movie is a Hollywood movie, just in Norwegian instead of English. OK an upper class Hollywood movie, but still has the typical unoriginality of Hollywood. The plot is 70% predictable, and the main characters are all so beautiful yet full of humanity. What else? Well, the actors are quite alright actually, so we need some more English language, and actors who can't act to make this a perfect Hollywood movie. Without those, it's watchable, but still nothing better than that.
Add Angelina Jolie and Robert De Niro (or worse actors, if you can find) and then even the language won't be able to make it Norwegian. The way it is, it's not a waste of time, but your odds of finding a better movie to watch are really strong. Especially if you've picked it just because it's not a Hollywood movie as I did, I can't say I recommend it too deeply.
A generous 7.5/10
