I'm in the no camp. The difference maker for me is that Christmas movies share a tone that die hard just does not.
It doesn't explore the 'magic' or Christmas in any way, but it is a story of redemption, with Christmas itself being the catalyst that re-unites John and Holly before the Gruber boys show up. That's some solid sentiment to me.
And the opening of the vault is a brilliant scene which invites you to join in the fun of the bad guys winning, starting with a Christmas joke and growing into Ode To Joy. It's way more evocative than any "let's open our Christmas present" scene I can think of, with maybe Danny getting Gizmo in Gremlins being close.
So, I think it's on the fringes, but it counts because ultimately, the best thing about Christmas is family (except that time I got Tomb Raider 2 on my PSOne).[/QUOTE]
