It's 100% just nostalgia but I love Jingle All the Way. It was my favorite as a kid and watching it (almost) every year during Christmas is a bit of a tradition.
As a bonus, as and adult I like how upset people get about it now. "Um actually, it's not funny because the neighbor is creepy and Arnie is a bad dad and if you think about it he and the other dude do a lot of illegal and dangerous stuff".
Nah...fuck it, it's funny and from a time you could make jokes about technically serious stuff without people crying about it.
This might sound weird but I saw it for the first time last year. For years it was a meme for how shitty it is but it's honestly not even close. I thought it was a pretty good Christmas film but got really stupid at the end with the jetpack and shit.
I dont think i have one. The christmas films i've watched recently are: krampus, let it snow, noelle, home alone, the grinch (jim carrey), last christmas, and not quite christmas but Frozen 1 & 2.
