Tried to fit too much in to the plot (spoilers)
They tried to fit too much into the plot. The film should either have been about a parent trying to reconnect with their child after deployment, in which case a male should have been cast, as overwhelmingly this has been and remains a male problem or they could have made a film about a female medics experience in Afghan (i.e. the other soldier attempting to force himself on her and her treatment as a woman, even as a woman with children. Having the two combined, takes away from both and doesn't allow either to be properly considered or developed and what you end up with is a rather superficial military drama
