People just don't appreciate the trashier things in life. In all seriousness though I'm surprised it didn't rate that well. How is this brand of trash and different from all the others that have done so well.
Doctor Who. If you give more weight to the Doctor as the lead character, but still count the companions as co-leads, it's arguably about 60% female now. But it always was at least 50%, the BBC is more progressive. Blake's 7 always had 3 out of 7 (humanoid) female leads.
