I Sif returns, Skye shakes, viewers yawn. Review by Brandon Wolfe Pity poor Jaimie Alexander. As one of the few members of the Marvel Cinematic Universe low enough on the totem pole to be accessible for TV, she keeps getting roped back into Agents of S.H.I.E.L.D. as Lady Sif returns this week for her second appearance on the series. It’s not that Alexander isn’t welcome on the show, but she very clearly is being utilized not because Sif makes perfect sense as a regular popover to Coulson’s tiny, earthbound corner of the universe, but because she’s a much easier “get” than a Robert Downey Jr. or a Scarlett Johansson, whose characters would make infinitely more sense crossing paths on a frequent basis with S.H.I.E.L.D. I guess you work with what you have. Anyway, Sif wanders out of the ocean one night in Portugal with no memory of who she is (because amnesia is a device used only by the finest of shows). It isn’t long before her superhuman exploits land on Team Coulson’s radar
