I found it thought provoking enough to actually dream about it last night. However I do agree with PP not giving more of a back story to each of them was frustrating.
You can see why Jalal & Ziyad went, Jalal wanting to be like his brother, Ziyad looking for adventure, Ushna caught up in the 'romance' of being a brave soldiers wife, it was Shakira that really jarred for me.
Clearly educated, had prepared by learning Arabic; but hadn't taught the son any??? Seemed to think for some reason that she'd be treated differently to other women. I also couldn't understand in the scene where she was treating Jalal; her 'husband' made it look as he was sneaking her in against the rules, yet other scenes showed her openly treating other male casualties. . . .
And then her attitude when been interrogated; of course she was going to be at least detained, why on earth wouldn't she be? I mean there's been enough in the news over the years of other returners been held, all very odd.
