I really enjoyed this film. It’s a sweet romcom with a cosmic twist and quite a few good jokes. If you didn’t see it yet highly recommended. You can watch for free on BBC iPLAYER until 25th January or thereabouts https://www.bbc.co.uk/iplayer/episode/m0012wqp/last-christmas
After 25th January and right now it is available on various platforms for £2.49.
