It’s combination of the three. The 18-34 demographic which largely fueled NWH gross, are less concerned about the safety at the movies. I do think also that without Omicron things would have higher grosses, in particular Sing 2, as the family demographic is not 100% there. Also, yes there’s an interest factor as I do think The King’s Man prolly have done the same.
I do think Matrix would’ve done much better if it didn’t face Spidey and had PLFs this week
