First of all, you certainly can make a film about love without sex. Second, I would expect nothing less from the good sister. You are appropriately sensitive to violence. The world is not. The horror of war cannot be overstated, so the implication of violence will not suffice. We live in times where super heroes battle in CGI backdrops with whole cities collapsing around them. No one is appalled, it's just a movie. This wasn't, this happened. If you can find me a veteran of this conflict that tells me "Mel got it wrong, it was much nicer than that" I'll eat my hat.
