Watch the original!
Whether this inevitable American remake is good or bad, the original 2015 Swedish film A Man Called Ove is a pure delight, and one of my favourite movies of the past decade.

This seems like a Let The Right One In / Let Me In situation. Even if the remake is decent, as it was there, is it really necessary for America to remake such a recent film that is so excellent in its original form? There’s something very lazy and almost disrespectful about it to me.
