Well, that's uplifting (not).
I think it's bloody awful.
They're all looking at the father at the beginning as if they're waiting for the next unpleasant drama to unfold; as if they never know when he might explode.
Like pp I also expected that it would turn out that the son was actually dead.
It's supposed to be about Christmas. Surely, it should be happy rather than horribly depressing.
As far as I can see there's a son who has a very distant miserable father so he buys him a record that he hopes will make his father show him a bit of affection and, goodness me, it actually works. his father gives him a hug. However, by Boxing day he's probably gone back to being the same miserable bugger he always is.
Not really sure what it's got to do with Christmas particularly. People buy present for loads of other occasions.
I fear the maker of this advertisement have ambitions to make gritty dramas for television or film. Meanwhile they're stuck making naff TV commercials.
