As pad-e says, I saw the lights ident before Home Alone for the first time (on the telly, at least). If I had one gripe, it's that they let it play in full long after the CA
has said what they have to say. Comes across like something has been mistimed. I'd say it'd be better for the CA to come in a little later, but it's still a while into the ident before anybody says anything.
That's nitpicking though. It's definitely one of the best Christmas idents of recent years. Even better when it precedes one of the greatest Christmas films there is.
