It depends what you consider the end, in the movie "social network" they managed to make an awesome movie with a young facebook.

Oh that's easy with a character piece, you start out at a low point (eg walking in to find FDA inspectors turning the place over) flash back to story of the meteoric rise during which you get to know the character (but not too well) and then end at a crossroads so the audience leaves speculating about what she would do and what they'd do if it were them.

It's a perfect role for Jennifer Lawrence since she can subvert her own stereotype. The woman's a genius.

Nobody will watch part three, even though it is split into two movies, so the ending won't matter.

> We don't even know how the story ends!

I think Game of Thrones has shown that isn't a problem.

When has accuracy ever been required in the pursuit of money?
