The success of Old Lady Harley may depend largely on what you want out of this new miniseries. If you merely crave an extension of the main Harley Quinn book, one that features a similar tone and sense of humor but a radically different setting, then Old Lady Harley delivers the goods. But if you’re hoping for a somber reflection on Harley’s life and legacy a la Old Man Logan or The Dark Knight Returns, you may come away disappointed. It’s a fun read, but not one that runs as far with the premise as it could.
Building on the initial Old Lady Harley storyline form the main series, this spinoff takes a deeper dive into the alternate future DCU where Power Girl is President of the United States, Canada is overrun by poutine-loving zombies and Harley is a few decades older and exactly as weird. The big selling point this time around is that Harley and her faithful sidekick/Deadpool clone Red Tool have to hunt down Joker, who apparently managed to cheat death yet again.
