I've personally watched lots of movies at Legacy. It is one of my favorite theaters. Until now, I don't remember ever seeing anybody from the gay community there. If they are there, they sure aren't the flaming flamingos you'd see in Oak Lawn. (San Francisco like part of Dallas for those of you unfamiliar)
I figure all the gays who want to see the movie will see it within the first two weeks, then it will die. Reminds me of when Howard Stern's movie came out years ago. All his fans rushed to see it and then it dropped like a rock after that.
