Did You Know?


The plot of this episode has many similarities to Charles Dickens' "Oliver Twist". See more »


When the Sewer King grabs a child and accuses him of "talking," he leads the child (wearing a white shirt and blue shorts) to lock him in the room with the lights in it. The child that had cried out (due to injury) had been wearing all orange. The boy in the blue and white clothes was the one who wrapped his ankle. See more »

"Hurry hurry hurry hurry!!!", and give this early episode a rewatch, it may be a little better than you remember!

Some have really seemed to take a strong dislike to this one and consider it to be one of the show's worst ever, but I sure don't, it's nothing amazing, but I have a special place for this episode because it was one of the first I ever saw as a kid, and it especially gives me a nostalgic feeling when I watch it. It is a bit weirdly written and has some scenes that do feel overly silly and come as filler that doesn't need to be in the story, such as the opening train sequence and everything with Alfred and the bratty street kid that Bruce temporarily takes in, but it does have a fun loony one-shot villain and a great musical score that adds a lot of emotional weight to the plot, as well as the usual terrific artwork. It's the real Fagin-like villain that makes the episode worthwhile though, while not in the same league as the main villain roster, as a bad guy he is especially heinous and does kind of strike a cord because of his cruel enslavement of and mental abuse of the innocent runaway children that he rules over like a twisted self-declared king. The voice actor gave an amazing thunderous voice performance and had a tremendous scary bark that conveys the tyrannical lunacy very well, and you quite understand how the kids would be terrified of disobeying him through his harsh punishments as well as his emotional blackmail, making them believe that they had to depend on him and had nowhere else to go and no one else to give them shelter. His craziness isn't quite as 'fun' as that of the Joker say, and out of all his villains, it's the actions of this vile little disturbed man that Batman clearly takes very personally and bothers him that little but more to where he expresses a desire to take the law into his own hands. And I love that, showing a little more open, more angry compassion about something than usual every once in a while gives Batman a little added depth. I always found this to be a solid involving episode and I still do, it's not great but I wouldn't lump it in with the other duff episodes at all. A respectable 8 ridiculous lines about frying chicken that prove that literally anything Kevin Conroy could say would sound epic out of 10! X
