Posted6/9/2021 5:23 PM The first episode of "Loki," now streaming on Disney+, offers glimpses of a clever sci-fi pastiche in between rehashed scenes from the Marvel villain's previous film appearances. Tom Hiddleston's god of mischief, the main antagonist in 2011's "Thor" and 2012's "The Avengers," took a convoluted path from the big screen to your living room, and this week's 51-minute premiere goes to great lengths to explain it. Of course, the hard-core Marvel Cinematic Universe fans already know it, and the uninitiated won't be able to follow it -- they'll just wonder why they're watching Loki watch scenes from his own movie. (This literally happens.)
