The Halloween-themed episodes of “The Simpsons” have always been a treat of spooky stand-alone storylines. On Sunday, the show surprised viewers with the resurrection of Apu. The beloved Indian Kwik-E-Mart operator had not been heard onscreen in almost a decade. Once voiced by Hank Azaria, he's now voiced by Indian American actor Sunil Malhotra. Apu’s surprise return is a remarkable twist to a long-running discourse about the character representing a painful stereotype to some South Asian Americans. Comedian Hari Kondabolu made the 2017 documentary “The Problem With Apu.” He commended “The Simpsons” on bringing Apu back.
