But morality aside I suppose I can see why taking out so many guys might strain your suspension of disbelief. Still you're rarely facing more than 5 or so dudes at once and the game forces you to be stealthy and strategize as opposed to just soaking up bullets. The combat isn't exactly realistic but I think it's still withen the realm of possibility, unlike, oh say, Uncharted.
It was a fun movie and definitely had some great moments but a lot of it felt super pandering. I didn't mind the pacing so much but this is coming from someone who sat through all three LoTR extended additions with rapt attention, so yeah I don't really mind if a movie meanders a bit. Also what was up with that female slaver who always had the mask on? It looked like Laura Cayouette it one close up but it couldn't have been her character obviously. It felt like something was left on the cutting room floor with that one.
