Obviously things differ by location, but I'm in a large, pretty expensive city (Seattle). I usually go to the Cinemark in Bellevue because they have IMAX. This is a nice theater in a nice area. A ticket to see Furiosa tonight, in IMAX, is $19.50. A ticket for a standard screen is $13.50. My recollection is that's pretty much what movie tickets cost 10 years ago.
I think the films just aren't enticing enough to steal eyes from streaming services, TikTok, etc.
