I missed seeing this when it was broadcast over Christmas and only discovered it yesterday on BBC iPlayer. I watched it expecting it to be reasonably amusing 'filler' TV but was happy to find that it was a lot funnier than I had expected. Both of the lead actors are great in it and had me laughing out loud (something I don't usually do to be honest). I was also surprised to find myself tearing up in a couple of places (again I don't usually do that). It was one of the best things I have seen recently and I wouldn't be surprised if Hollywood makes an extended, big budget, noisy, whacky, over the top version of it. It could never have the charm of this original though. I can see myself watching this every Christmas. Kudos to the actors and writers of this little gem. Highly recommended.
