I love it.
Instead of such nonsense as e.g. an entire street/neighbourhood creating a single massive snowball, or spogs bouncing around an it-could-only-possibly-be-the-inside-of-a-TV-studio environment on Christmas puddling-style spacehoppers, etc etc etc...
...we have something actually resembling what most of us mere mortals might be doing with out time during the festive season (i.e. not very different from how our lives are for the rest of the year, just with the addition of e.g. Christmas jumpers or whatever).
You can bet your granny that the various sets of people/characters seen in the John Lewis-esque promo will each have an ident.
Therefore there'll presumably be a damn sight more than literally just one-or-two different festive idents. Which I'm sure hasn't been the case for years.
If you want an innuendo, I'll give you one.
