Back when The CW was known as The WB, they were so desperate to replicate the success of 'Smallville' that they greenlit a series based on the DC superheroine team Birds of Prey that had very little to do with the actual comic book. In fact, the premise was so convoluted, it required an opening sequence where Alfred explained who everyone was every week.
Set in "New Gotham" (what made it "new" we'll never know), the show hinges on the premise that Batman has left his city for reasons that are never fully explained. So his crimefighting mantle is picked up by Huntress, who is -- wait for it -- the offspring of a torrid love affair between Batman and Catwoman. Oh, also she's a "metahuman" with special abilities despite the fact that neither of her parents have powers. She's joined by Oracle, who had already been Batgirl but was now confined to a wheelchair thanks to being shot by the Joker. (The brief moment of Joker shooting Barbara Gordon/Batgirl in the show's opening sequence is probably the closest we'll ever get to an adaptation of Alan Moore's graphic novel 'The Killing Joke.') Also there's a young metahuman named Dinah, who is the daughter of Black Canary and has telepathic abilities because, who knows, they wanted a Jean Grey type probably. Oh, and in the unaired pilot Sherilyn Fenn played Harley Quinn (Mia Sara played her in the actual show) because why not toss her in at this point as well, right?
Looking back, 'Birds of Prey' feels painfully dated in an early '00s way with its "alt rock" theme song and lead actress who was clearly channeling Jessica Alba in 'Dark Angel.' But Batman eventually came back, right? Nope. In the final episode, Alfred calls "Master Bruce" and tells him how great his daughter is doing. So basically, it's a Batman show where Batman goes on vacation and makes his kid pick up his slack.
