I'm on mobile so I can't thoroughly drag you for this, but you literally just said you didn't give a shit about the whitewashing. It's not in your place to concot handwaved excuses for something that clearly affected the perception of this film to people that otherwise might have seen itThe conclusion to take away from this is to make better movies. Reviews don't make or break a movie but combined with WoM it can sway the results in one extreme or the other.
The props were great, wish there'd been more of that, instead we got 120 minutes of mostly boring action with little substance beyond that. The movie punches you in the face with subtlety. For instance they don't just hint at what GitS is supposed to mean they literally spell it out for you, multiple times, throughout the movie. They spent all their exposition dump in the beginning on pointless stuff that they explain in the movie agsin anyway. Then disregard the city the movie plays in altogether.
Personally I'm not upset about ScarJo's casting nor about the whitewashing, but the role was bungled either by her, the writer or the director or a combination thereof. I forgot they changed her name so wasn't surprised about the twist either.
It's funny you haven't seen the movie but still see the need to compare it to Marvel movies with snide remarks.
