What is the nature of evil? Fussing over that question can seem an impossible quest but genocide and serial killers remain perennial subject of scrutiny for me. The first season of “Mindhunter” offered a unique entry into the latter category of evil, by adapting the same-name true crime tell-all by John Douglas and Mark Olshaker, recounting the FBI history of developing serial killer profiling, which I read over two decades ago. Mucking around with the characters a bit, the first TV season was horrifying, troubling, but strangely, effectively informative and revealing. So I approached the second season with trepidation: could it possibly continue the high standard? Well, I can trumpet that the first episode equals or betters its predecessors. Quickly refreshing the plot and re-introducing the core three characters, the intelligent script plunges us into a new, apparently supportive boss and a new horrific crime and, of all things, an in-jail interview of Son of Sam. Moody cinematography, great acting, edgy music, and the promise of more to come … I can’t wait to get to Episode 2!
