This movie is such a waste of time. The comic book 'The Killing Joke' was such a great comic, but it wasn't one to be adapted into a animated film. This movie is so poorly made, with frames of animation going slow making it feel like low frame rate, especially when Batman is walking through the prison to the Joker. This movie is really depressing, showing the origin story for how the Joker went mad, it's a very sad tale, and is not at all fun to watch, and at times uncomfortable. Kevin Conroy is serviceable and does as good as he could've. Mark Hamill is a major standout delivering a performance he's clearly wanted to take on, ironically the only fun part of the movie involves him doing a musical number which is so bizarre and weird that it's fun. Other than Mark Hamill's performance this movie is really bad. Really would've preferred a Mark Hamill audio-book of the comic. The R-rating was a big advertising gimmick for this film, and it is not deserved at all, there's lots of blood and some disturbing imagery in the first 30 minutes, but after that nothing to justify the R-rating. This movie is quite an accurate depiction of the comic, but since the comic isn't long enough to make a feature out of, they add 30+ minutes of Batman and Bat-girl, it's purely in there to make you care about the character of Bat-girl, except you don't because the first 30 minutes is an unnecessary cliche filled side-plot that has nothing to do with the comic and even features a disturbing scene with Batman and Bat-girl towards the end. Did I mention that the Joker is the most fun thing about this movie? That shouldn't be true since Joker should be horrifying. Overall this film is a dark miserable mess, only would recommend to the fans of the comic since after the first 30 minutes it becomes an accurate depiction of the comic, but it's miserable and depressing. To the average Batman fan wanting a fun Batman story, I do not recommend this dumpster fire.
