Very good! I thoroughly enjoyed this.
You never really know what to expect from Xmas films, especially those with (no disrespect intended whatsoever) unrecognisable (to me, of course) leads and those that are straight-to-streaming. 'Your Christmas Or Mine?' is, thankfully, a rather swell festive flick.
Asa Butterfield and Cora Kirk are a good pairing, though given the plot don't actually spend too much time together onscreen. Butterfield has more to work with, his side of the plot is very much more fleshed out. As such Kirk does well with her scenes.
As noted this is my first time watching Butterfield [actually, technically I've seen a ~13-year-old him in 'Nanny McPhee and the Big Bang' - who knew?] and Kirk, though behind those two there are many a well known face that I spotted. Daniel Mays, Angela Griffin, David Bradley and Alex Jennings, plus one or two others, are actors I've seen elsewhere. The support cast are excellent, here.
It's amusing, very nicely paced and has all the necessary cheesy Christmas vibes - though, to be fair, it's not Hallmark Channel-esque cheese, it's just the usual strong sense of holiday cheer... which is what you'd want from a production of this ilk to be honest, at least I do.
