A Christmas Story is not usually mentioned along with the great comedies of all time. I'm chalking its lack of respect to being a holiday film.
Every Christmas, TBS runs a 24-hour marathon of A Christmas Story. It's the perfect Christmas film: there's rarely a slow scene, and the narrative is so familiar and tangential it allows you to skip in an out. I've been watching all day, here and there, and right now Ralphy is fantasizing about returning home, blind from soap poisoning. It's a tremendous scene, one that would've been the standout in comedies these days, and been played over and over in trailers. In A Christmas Story, it's a throwaway.
Three cheers for TBS! I hope they never end this tradition.
