Far from perfect, as the story might be an adaptation of the "woman needs to be saved by brave (American) military men" trope, but it's one hell of an adaptation. Despite what some reviews seem to fail to notice, the main character of Amber is tough as nails, runs circles around her captors, breaks out of a prison camp and is only caught due to her good heart (making her the only positive hero in the story, with the two guys being most definitely antiheroes), and Jessica Ann Collins portraying her is brilliant in the role, layered and realistic. Then there's the unique portrayal of her trauma, PTSD, feeling of guilt, leading to a very ambiguous ending (surely not a happy one), with all 3 main characters wondering if perhaps all they've done wasn't a huge mistake. Any other show or movie would have called it a day after ep. 9 and be content with being a solid action thriller, but the fact they explore the actual consequences of everything that has happened until that point, both psychological and political, makes this show something special and definitely worth watching.
Then there's the cinematography, the casting and the great score. Oh, and the US are actually the bad guys here, how often do you get to see that in an American show?
I had low expectations of an Apple show with a mostly unknown cast but I didn't regret it for a second.
