I've just watched the last episode and I thoroughly enjoyed it. I even take it back about the acting. 
I thought it was clever how the Palestinian was killed by the bit of the Stein bomb that killed Atikas family.
Talking about the 'bag', wouldn't it have been a cliff hanger if the bag he dropped was the one the Palestinian ,who had Nessa raped and killed her family, showed Atika before he stabbed her. Could have been a new series in itself.
It was a clever plot and different.
