In 1997, Batman: the Animated Series was given a total make over and dubbed The New Batman Adventures. The characters were given a more modern and stylized look and the adventures became a bit more kid friendly with the introduction of Tim Drake as Robin and Batgirl as a regular cast member. The series launched with this Christmas special.
Everything that was wrong about Christmas With the Joker was corrected with this episode. The animation is way smoother and the new look compliments the characters a great deal.
The story of Holiday Knights is also a better one and is written by Paul Dini (Lost). It is three mini-stories of events that happen during the two weeks before New Year's Day. First, Harley Quinn and Poison Ivy hypnotize Bruce Wayne and go on a wild shopping spree; then on Christmas Eve, Clayface is caught shoplifting by Renee Montoya, Harvey Bullock and Batgirl; and finally, on New Year's Eve, the Joker has a plan to blow up Gotham City when the clock strikes midnight!
It is charming and fun and fits in with the rest of the series, unlike that other piece of garbage I mentioned before.
