"So why has BTAS eschewed this cycle?" asks Daniel Dockery. "Aside from the fact that it is, as anyone who’s seen it will attest, a really good show, it’s also the series that would blend the macabre Art Deco Gotham City of the recent Burton films with a film noir-ish sensibility, making it look unlike any other show on TV at the time. After the 1980s, a decade when most cartoons mainly served as extended commercials for corresponding toy lines, Batman’s adventures were pulse-pounding and iconic. Heck, it’s the series that made Mr. Freeze interesting, and the one that birthed the character of Harley Quinn, who shot up the ranks of identifiable DC Comics characters in a way not seen since the 1940s."
