Well, you see what you see in it. I see a miserable family having a Christmas nobody wants or enjoys, where the women do the cooking & housework while the son slopes off to his room & Dad swiftly abandons tidying up to play with his new toy & feel sorry for himself.
I said he'd given up on his son because he doesn't seem to have any memories of the kid between being a little boy & being a teenager. I expect Mum spent those years doing the school run, feeding the kids & talking to them, though, so that's alright.
As I say, I'm not a natural JL customer, but that's the impression I got from a first viewing. Maybe I should watch it again to check, but I honestly couldn't bear it.
