I watched the movie six times in a row and was not able to discern a single homosexual, lesbian, bi-sexual or trans-sexual(though the space person does leave some question).
This movie is a homophobic outrage and shows the mono-chromatic narrowness of Hollywood.
Political correctness at its worse. Why can't we have a movie with all normal straight people?
Not a single black person to be seen as well. However, if there had been a token black in the film who was killed by the alien, then there would be the inevitable post from someone claiming this movie was racist for bumping off a black person.
I'm a totally bitchin' bio writer from Mars!
