My dude. Funniest Christmas movie there is.
While the subject of the movie is getting home for thanksgiving, it's not exactly a thanksgiving movie. The movie 'Dutch' with Ed O'neil(Al Bundy) is amazing. It's not as vulgar as Bad Santa but given its time period, its the Bad Santa of thanksgiving movies. Again, it's not really a thanksgiving movie per se, but I'm not really sure thanksgiving movies exist in the first place. So, closer than most.
Indian in the cupboard, should make it a thanksgiving movie.
