Something overlooked by everyone when adjusting the old movies for ticket price inflation from 1979-1991 onward is the population of NA has increased by a great deal. Even though ST09 sold the most tickets of any Star Trek movie, the percentage of the population that went to see it was much less than TMP/TWOK/TVH maybe even TSFS?
True, but movies also have a lot more competition from other sources of entertainment today than they did back then, and pirating is a much bigger issue now. Anyway, there's no need to set the films against each other. The first four Trek films and Star Trek
were bona fide home runs in the domestic market by the standards of their respective eras.
