'No one leaves' ad for After Eight

I was impressed by this advert as it shows festivities and a cool party atmosphere without succumbing to the conventions of many adverts that show partying in an over-the-top wild and pretentious way. It appears that fun is being had by all and brings a bit of a warm glow in the winter season.
It's the first television advert for After Eight chocolates in eight years and I think, this time, ad agency JWT have hit the spot.
