Honestly, I did not buy this DVD after seeing the episode listing. I already own the complete series' of "Batman: The Animated Series", "The Batman", "Batman Beyond", and "Batman The Brave And The Bold".
The episode selection was very poor indeed. A great example of this being "All Hail The Tornado Tyrant" which ONLY features the Joker in the teaser portion before the theme song starts. Why include a Brave & Bold episode where Joker is only in the teaser instead of say, "Joker the Vile & Villanous" where Joker actually takes over the whole episode! Or the two parter "Deep Cover For Batman" and "Game Over For Owlman" which features Batman teaming up with the Joker in both episodes (although one is an alternate reality Joker as a hero).
We also don't get any Joker episodes from Justice League, and the episodes from Batman Beyond don't even have the Joker at all and could've easily been remedied by using the Batman Beyond movie "Return Of The Joker".
The three "World's Finest" episodes could've been replaced with "Triumvate Of Terror" from "Brave & Bold" and still had room for two other Joker episodes while having thrown in Wonder Woman and the Cheetah to boot!
The collection also leaves off classic Joker episodes "The Laughing Fish" or "Mad Love", or from "The Batman" episodes like "Topsy Turvy", "The Laughing Bat", "JTV", "Two Of A Kind", or "The Metal Face Of Comedy".
Unfortunately, this collection really lacks the best of the best Joker episodes.
