Home Alone
This is THE Christmas movie for me. If I could only watch one Christmas movie ever again, I'd choose this one. It has everything. It's hilarious but also heartwarming. Truly iconic performances from Macaulay Culkin and Catherine O'Hara. And the physical comedy from Joe Pesci and Daniel Stern is second to none. Stern in particular has some of the funniest line deliveries and reactions I've ever seen. That bloodcurdling scream he does when Kevin puts the spider on him kills me every single time. I really like how all the little details line up to explain everything and it all just perfectly falls into place. It's honestly just a perfect movie and I can't go a Christmas without it.
