This movie actually has a well-made feel to it, like when everybody knows what they're doing and it's not just a studio spewing out TV fodder. MJH is always watchable, and there's a solid supporting cast.
The Christmas theme is not over-cooked and there isn't too much vomit-inducing schmulzt (is that a word?) apart from one scene involving some fairy lights and ice skates.
All the characters are solid and well-rounded, except perhaps David Martin who is a little too male-model for it to be believable. This doesn't really spoil it, however.
There are some genuinely funny scenes, notably the Christmas dinner, edging just on the right (moderate) side of farcical. The characters are likable, the story has a warmth to it, and there a zillion worse Christmas rom-coms with far bigger budgets. So, well worth watching.
