Oh yes Flossy, but during the day (usually before 6:00pm) you can see movies at "matinee" prices, which is about half to less than the evening rate.
Also, the theatres tend to be less crowded during the weekday due to kids in schoold, folks at work and so on.
I do not get all the hub-bub about a movie, but it seems we Americans have placed some sort of wierd value on "being first" to see a movie. Really strange people I tell ya.
