Well - I had thought it would end up with Erik staying and playing happy families.
But I think all the reveals about how people saw him, ie even his girlfriend just happily junking all his stuff and wanting to do more than slum it in a container.
But can someone explain, in the fight seen between the younger twins, Adam says "did she know" and Erik hesitates and then says "no she didn't". But didn't what? Is the implication that Erik tricked Ingrid into sleeping with him? I had thought that when he left (as a young man) she was already pregnant and then married Adam thinking even if Erik came back he would be useless as a father / husband. So did I get this wrong?
But one thing I did get right (sort of) was whether it was a comedy or not. Apparently it was written as a comedy but it was only filmed much later and became this just 7 days of the illusion of the life being led not being what it was meant to be.
There is an article in the Sunday Times which is where I saw this. And apparently they aren't talking Norwegian but some dialect, and many of the cast are from the region rather than professional actors.
Really glad she gave her dad the boot!
