Retail square footage is not cheap wherever you go. Even rust belt is getting a few bucks a sq foot and average is more like 15-20. So a couple thousand square foot theater is around $10k a month and probably more like 20-40k.
I don't know, maybe theaters get a super good deal as anchor tenants. But doesn't seem to add up that $1,000 a month on a projector rental is a driver of price increases.
