I don't get too bent over any I can think of, but I'm not sure I've ever been able to watch Disney's "Babes in Toyland" remake/reimagining from beginning to end. That's discounting, of course, the scads of modern Christmas-esque movies I know better than to try and watch.
Favorite "A Christmas Carol" adaptation? "Scrooged".
Favorite Sleeper: "Joyeaux Noel"
