Others have wondered the same, including me upthread, but I would say the audience in non-COVID circumstances would be, in the main, families and older people, mainly women, who would come out because they remember the old movie and know Spielberg's name, and people who would be influenced by the great reviews (who would also skew older). As pointed out upthread, these are the people most likely to be spooked by the virus. Not much anyone could do about that.
