This is a pretty good documentary about villains and how they define and/or compliment their respective heroes. I felt it seriously needed a little more focus in some areas and since there's no special features, it feels like it's missing maybe some form of villain encyclopedia of the relatively few mentioned villains (mostly the mentioned one's are the primary nemeses of DC's top heroes) and the people we see discussing the villains.
Overall I almost wanted to four star this, but I couldn't because of one celebrity. Literally every single time DC overrated (once he was great but he's as bland as Marvel's Bendis now) superstar Geoff Johns appears to discuss a villain, this huckster does not technically offer insight into the psyche of the villain, or the villain's motivations, but he simply discusses that said villain is intriguing because "there's a moment where [villain] did [action] and it's a great moment". The moments of greatness from the villain is inevitably not something fantastic but a moment or origin Geoff himself actually wrote in so it's a bit of fanfiction self service in my opinion. The villains he discusses are Black Manta, Sinestro, the Aquaman race he created for New 52, Amanda Waller (who is definitely nit really a villain to my knowledge), Flash's Rogues, and several others. Taking into account Zoom (Reverse Flash II), Darkseid, and one or two other brief notes from other creators, this documentary should have been called "Necessary Evils of Geoff".
That said it's not truly awful and the end talks about the lukewarm New 52 (painted as loved of course) and the then planned currently in the process "Forever Evil" event (I kind of laughed at the part about Rogues writing their weapon abilities on their DNA, because Forever Evil undid that part when the film released).
