By God, this is as definitive as a war film gets. It's on every year, and is as much a part of Christmas as getting drunk and Monopoly. Everyone in this Sceptred isle knows the theme to Dam Busters, and it causes more people to stand up and salute than God Save The Queen. It has moustachioed R.A.F boys, politely bespectacled scientists, laughable special effects, and an entirely predictable ending. It's a British institution, and I don't know where we'd be without it. You can keep your devolution and your New Labour, I've got Dam Busters and I'm not bloody budging.
