Watched the first five minutes: if I ever watch more, I'll add to this. I stopped because of the implausibility of the action. In the opening scene, (a) how did whoever exploded the bomb know that the "bot" wagon would break a wheel? (b) why not simply fix the wheel and sent the bot, rather than sending a man who dies (c) when the bomb exploded, why remain standing? dive, prone, with feet facing bomb. Second scene: why don't the soldiers in the apartment simply call or radio the bomb squad? Why do they remain silent until the new Sergeant sticks his head in the door? An overall question: why bother with a bot? Simply shoot at the bags of explosives until they explode.
