As supervillain powers go, “turning off the lights without having to get out of bed” is dubious. You can jazz it up like this week’s Agents of S.H.I.E.L.D. episode did and claim that what Blackout is really doing is absorbing energy, but that still means your villain’s greatest weakness is A Bunch of Flashlights. Thanks for the takedown, trick-or-treating group of kids! We’ll call you next time he escapes.
If this was earlier on in the season, I feel like Agents of S.H.I.E.L.D. would have tried to hang its entire episode on this monster chase in an attempt to dazzle the viewer with the concept alone. It’s a sign of the continued growth of the show that “The Only Light in the Darkness” now pushes that to the margins in favor of spending its time with our non-super-powered—but more interesting by the week!—team of agents.
