YMMV: Batman Beyond: Return of the Joker
- Awesome Music: The soundtrack has the Humble Brothers Remix of "Crash" by Mephisto Odyssey featuring Static-X.
- It even includes the music video for the original version of the song as well.
- Complete Monster: Joker gets a prime piece of villainy to stick on his trophy rack from this movie by capturing and subjecting Tim Drake to some truly vile torture.
- Crosses the Line Twice: Almost everything the Joker says or does.
Joker: If you don't like the movie, I've got slides!
- Ensemble Darkhorse: The Jokerz in this movienote , especially Dee Dee, are all extremely popular among the fandom. This is likely the reason they were included in the Bad Future episode of Justice League Unlimited.
- Foe Yay: One of the biggest examples of Batman/Joker. To put it bluntly, Joker kidnapped one of Batman's "sons" with the intention of molding him into his own "son".
- Heartwarming In Hindsight: See the cameo bit on the Trivia page? Considering all that's happened between them since this was made, note it's nice to see that there's at least one version where the two of them finally settled down together with their own life.
- Hilarious in Hindsight: The Joker crashes a high-rise party, and escapes because Batman has to save a guest from falling. Sound familiar?
- Inferred Holocaust: On two occasions, Joker uses a gigantic military orbital laser to carve a swathe of destruction through Gotham. Civilian casualties are never mentioned on either occasion, but it's a giant military laser carving through a major city, often going right through buildings. One can only imagine the death toll. The commentary track notes that the laser miraculously avoided hitting a single person.
- Magnificent Bastard: Joker, again. One of the rare cases where it overlaps with Complete Monster.
- Memetic Mutation: Oh, what the heck, I'll laugh anyway! HA HA HA HA HA HAA!
- Moral Event Horizon: The movie gives the Clown Prince of Crime a rather infamous line-crossing moment: he kidnapped Robin, tortured and mind raped him for three weeks, mutilated him, "fixed" him up as Joker Jr., implanted a microchip doctored with the Joker's DNA into his body, and invited Batman over to see his work in detail (which included a home video of the boy's torture labeled as "Our Family Memories"). He then reveals that he's learned Batman's secret identity, mocks him for it (and for not having the balls to kill him after all this), and knifes him before he tosses "J.J." a spear gun to finish him off with. Also worth mentioning that this particular MEH crossing was the former page picture.
- Even for the Joker, the events of Return of the Joker were extreme. He was already dangerous and psychopathic, but the very nature of how he did it turned him into. Not even Harley Quinn gets a get out free card after helping with that. Although she survives anyways, thanks to her quasi-superpowered vitality after Poison Ivy made her nervous system immune to all poisons back in Batman: The Animated Series. Even Mark Hamill, who had been voicing the Joker for years at this point, felt uncomfortable with the role this time.
- Overshadowed by Controversy: The film will forever be remembered for two controversial death scenes (Bonk's and the Joker's), which were first heavily altered along with other scenes before it was released in 2000, in an attempt to tone down the violence due to being pressured by criticism from Moral Guardians and Media Watchdogs for violence in films during the fallout of Columbine; and then eventually brought back in 2002 when the Bowdlerised version didn't help matters but only caused unrest among many Batman fans that lasted for over a year.
- The Problem with Licensed Games: The PlayStation and Nintendo 64 versions had bad music, bad graphics, clunky controls, repetitive boring gameplay, broken combat, and can be started and finished within a half hour- 'seriously'- which is why it was given lowest scores from GameRankings and Metacritic. The Game Boy Color version fared a little better, however, but some reviews are mixed.
- They Wasted a Perfectly Good Plot: The film made it look like the new Joker was Tim Drake, who had finally succumbed to his madness after the torture and brainwashing inflicted by the Joker long ago, and adopted the Joker persona for himself. This would be believable in the context, it would be much more powerful and tragic than the actual story, and it would give the Joker the last laugh from beyond the grave, which would be in keeping with his presentation in the movie up until that point. It would actually have made a pretty good Batman film. Instead, there's a suspension-of-disbelief straining explanation about a mind-control chip and magical DNA.
- On the other hand, even before this movie came out, you had a wide share of technology and genetics from both the Batman and Superman shows; even if CADMUS and Justice League were only a twinkle in Bruce Timm's eye. Not to mention the idea of a former Robin turning into the new Joker was done in Frank Miller The Dark Knight Strikes Again, where Dick Grayson off all people tries to kill Bruce and his superheroed allies, which was one of the most criticized plot points in a whole sea of them.
- The Woobie: Tim Drake.
