As the superhero genre has exploded over the years, more and more holiday specials have arrived during this time each year. Whether it is movies set during the season in the background to add atmosphere to the story or episodes dedicated to celebrating the holiday season and its meaning, there's no shortage of superhero flair to enjoy during this time of year. DC has a fair share of them, too. Perhaps the most notorious is Tim Burton's dark and twisted Batman Returns, while Shazam! is another DC film that occurs during Christmastime to evoke the family element. Even more recently, Merry Little Batman was just released on Prime Video. However, "Christmas with the Joker" from the iconic Batman: The Animated Series remains the best superhero holiday special.
