Ok ok let me clear up the scene thing for you Shambler as your powers of observation do seem a tad lacking :
First - you see Johanbitches face at 19 seconds of the scene which is as soon as she enters the scene :

its the flickeringcamo - you recognise her mug clearly - this is the "oh no the audience is so dumb they might not understand whats happening and get frustrated and vomit their popcorn in rage if they have to wait 40 seconds to understand" moment. + more Jocunt face-time bonus.
Second is not about shortening the scene for gods sake - its the TECH - the camo tech is a TEXTILE which turns the wearer transaprent, ergo you need some of this textile over your FACE for it to work...just like the bodysuit suit she is wearing...in the live action the tech works what ? how ?
It magically spreads its invisi-semen over Jobitches face somehow ? Then there should at least be a shiny scheen of invisigoop all over her face to be wiped off.
No - the answer is they threw out any logic or care for the world building of GITS in favor of jobitch face time, because you know, they are banking on this "talent" investment hard and also they seem pathetically untalented/dumb/lazy in finding ways of allying their interests with the ones of GITS.
The worst of it is the character is recognizable enough in the anime in a subtle but perfectly decent way too for anyone *paying attention* : the outline of the haircut in the light refraction of the camo.
The timing issue is a bollocks excuse shambler, they can def accelerate the textile pulling back, its not to save time, they did plenty of that already by removing the bad dudes attempt at defending himself with the knife.
And no nothing against Scarlett Johannson per se , direction, production etc are the big problem as nitin says- replace with any actress I dont care, asian or african or whatever - I am of the opinion some liberty can eb taken with this - the important part if to portray the alien-ness of the Majors body - that attempted sexyness which kinda fils due to the bodies weaponized nature - its slightly off-putting outlandish moves etc, you see moments where the joints and skin stretch out really weirdly etc. Its a whole central theme of GITS - the Majors relation with her synthetic body - something the movie seems to pretty much blow off so far wth Jo-looser's performance there.
She is not the problem other than she is definately not throwing her wait as an actor of higher caliber and integrity would in insisting on being true to the character they are portraying. (Heath Ledger(rip), Caprio are examples amongst others of actors who seem to give a fuck, whatever their motive is for this)
