Batman Beyond

Batman Beyond (also known as Batman of the Future in Europe, Latin America, Australia, and Asia) is the successor to Batman: The Animated Series/The New Batman Adventures. It ran for 52 episodes from January 10th, 1999 to December 18th, 2001 on Kids' WB.

Plot
40 years in the future, and 20 years after Bruce Wayne’s retirement due to his failing health, his secret is uncovered by a troubled teenager named Terry McGinnis. After McGinnis' father is murdered by the man who took over Wayne's company, McGinnis dons a high-tech Batsuit and, with the help of a now-elderly Wayne, becomes the next Batman.

Why It Goes Beyond

 * 1) The idea of a futuristic Gotham City is top-notch.
 * 2) Great voice acting, especially from Will Friedle and Kevin Conroy.
 * 3) The characters are likable such as Terry McGinnis/Batman, Bruce Wayne, Max Gibson, Dana Tan and Commissioner Barbara Gordon.
 * 4) This show does introduced new villains such as The Royal Flush Gang, Blight, The Jokerz, Inque and Shriek.
 * 5) Chilling plot twists.
 * 6) Powerful music score.
 * 7) Badass Theme Song
 * 8) Amazing animation that has that kind of "tech-noir" feel to it.
 * 9) Plus, a Cyberpunk batman sounds pretty cool!
 * 10) *Along the Cyberpunk and even few Biopunk aesthetic, themes, and tropes, does end up actually works in the show's universe.
 * 11) Awesome action sequences.
 * 12) The premise and setting are more mature and intense than that of Batman: The Animated Series.
 * 13) Its direct-to-video movie, Return of the Joker, is also entertaining to watch.
 * 14) They also spawned a spin-off series called The Zeta Project, in which the story from the episode, "Zeta" continued in this.

 * 16) "Never again".

Bad Qualities

 * 1) It was abruptly cancelled after 3 seasons, despite a fourth season being in the works. Thankfully, one plot element from the cancelled season four, ended up being used in Justice League Unlimited as an apology for the Batman Beyond fans.
 * 2) The tone of the show could sometimes easily frighten young viewers.
 * 3) The characters like Terry have had difficulty integrating into main-stream comics.
 * 4) Nelson Nash is a rip off of Flash Thompson from the Spider-Man comics. Unlike him, he ignores Terry.
 * 5) In addition the show could feel more like a Spider-Man one than one of Batman, given that the protagonist is a superhero who is still in high school, lives a double life, always need to make up excuses to leave his friends and even has a bully who hates him but loves his super heroic alter-ego yet eventually becomes one of his friends.
