What do you think causes it? Not sure if reluctance is the word. But what makes them hold back from telling the complete story for these characters?
Well, we don't know how much was shot for the gay storylines and how much of the footage hit the cutting-room floor.
For these sci-fi films that are marketed to teen males and twenty-somethings, I'd use three words - box-office receipts.
But how many of these guys (teens plus) know more than a little about gay sex?
I'd say that the filmmakers are deceiving themselves.
