Saw some horrible reviews for this little curiosity and decided to give it a go, and was delightfully surprised by how well it works. It's a really nice low-key, off-beat little Christmas special. I loved watching it, and wished I'd done so at a more seasonal time.
I'm guessing the low scores are mostly from people who were expecting a tightly-scripted laugh-a-minute Bill Murray vehicle, but that's not what this is at all. As you'd expect from Sofia Coppola, it's a sort of mash-up of Lost In Translation and a Bing Crosby special from the 1970s, keeping the nice songs but replacing the saccharin with something sadder and more soulful.
It's not going to be for everyone, and clearly isn't ever going to be a mainstream hit, but if you've ever had to spend a Christmas far away from friends or family then this might be the film for you.
