tbh, i find kristen the only one with the consistent acting throughout the movie and her accent was the only one going on solidly (just so we're clear, till this day the only role i find kristen's acting good was in the runaways and now in this). i was legit surprised how well she did it having in mind twilight and her other work. if anything else (since acting is a subjective thing), her accent was spot on so i really don't get the criticism of it (and from the reviews i've read, if anything, they did say only positive stuff about it).
charlize was not so good cus she was all over the place with the constant yelling so at points she seemed plain silly, chris's accent was awful and all over the place (then again, i found thor to be weakest of the dc comics movies due to his and natalie's acting). in general, i think it's just the rookie direction and possibly not knowing how to direct actors with a script that had holes?! personally, i just started thinking about it after a while, the whole movie just doesn't stick with you after you leave the cinema....
the sequels i saw talked about year ago had snow white in plan - i think they also started with snow white and .... but i can't remember how they were called. i can see where it could be heading with her - probably in regards to her reigning the kingdom and obstacles she might have...it's not hard to imagine, tbh, but that's just me obv. i think kristen did sign up for a possible trilogy.
She was supposed to be completely hysterical. She was not supposed to be Meryl Streep scary in the devil wears Prada but completely mad/nut case. The problem is the way the whole thing was put together. You had SW+Huntsam doing their stuff - Charlize screaming like a mad woman - SW/Prince doing their thing - Charlize screaming like a mad woman. Kristen accent was def better than Charlize but then...could someone record how much/how long she talked in the entire movie? The script was flawed, the director had just too much on his hands or a first time and Universal over-hyped it and now word of mouth is killing it...
