Well, it's so inaccurate that you can tell from the start that it is going for statement over biopic.
And it almost seems like it should be titled "The Unstoppable RBG" as she comes across as right all the time, faultless, stronger, smarter and more capable than anyone to the point where she can argue a case, preform brain surgery, and create the rocket that got us to the moon, in a single night without breaking a sweat.
She's more perfect here than Mary Poppins and it makes the film sort of unbelievable. Ginsburg is human, I'm sure she had to struggle to over come more than just the evil White Male patriarchy, but even that she effortlessly dismantles.
Halfway through the movie you expect her to wear a cape and fly away, just to prove she can out super Superman as well.
In a Biopic you kind of expect to get to know the character, to see their ups and downs. Instead, however, what you get is a golden god with history rewritten to add a healthy polish.
