You are missing one very important point, If most of the girls will go for watching movies then who will bear expenses of tickets and popcorns so 50% of male population will always be there
And then there are few crazy folks, just to cite an example, My group of frnds force me to stay late in office on Friday and take me to multiplex directly. It doesn't matter which movie has come up. I remember I watched 2 movies with him where no more than 5-6 peapol were in the hall and once we end up watching Kids animation movie "Hanuman 2" where except us parents and kids were there
