The Conjuring
To be entirely honest, I don’t think The Conjuring would be as terrifying in a pandemic as some of these other franchises, but it’s only because the premise doesn’t get much more terrifying. Dealing with active malevolent spirits in the midst of a pandemic would be a nightmare, especially when there’s no real reprieve from them during a shutdown. Oh, the crazy ghost in your house that won’t stop rocking in the creaky rocking chair? Too bad, you can’t leave the house.
