One of the friends I’m seeing “Thor: Ragnarok” with for my second time told me that he hadn’t seen the second Thor movie and asked if that was going to be a problem. I filled him in on the important developments but also insisted that there was a particular scene – Loki’s death(?) scene – he needed to have watched for something in “Ragnarok” to make sense. So I sat with my friends outside the restaurant where we’d eaten dinner and showed them Loki’s death scene from TDW on the YouTube app on my phone.
