Blame the ladeez they love the soppy stuff like Twilight and attend in droves (lots of pretty boys see). Then when quality comes like this, intelligently written/made, with tons of atmosphere, suspense, drama, action plus great great acting, it is somehow ignored by the female gender (not all but the vast majority) because it doesn't have "Gasp" any romance in it!
I may not speak for the entire globe here but certainly england, they're all still watching dirty dancing and mamma mia over here for gawd sake....!"!"!"£££$£"$£????
