People think she's an asshole for interfering with the vision of her directors but a lot of her observations were spot on, like her takedown of Aloha:
It's actually simple.
Studio execs are not artists, and don't know what it actually takes to make a coherent movie. Russel Crowe explains it best right here.
Rudin echoed Pascal’s criticisms, which caused Crowe to fire off a distressed reply to Pascal and Rudin: “Don’t really understand what you guys are saying here,” Crowe wrote. “Been chasing everybody’s notes for a year, most of them conflict with each other… and this will end with the same people, arguing over the same conflicting notes, in the lobby of a theatre where we’ve previewed. Mostly this all sounds like French to me, very elegant, but not a language I can fully translate. Plus, I’m gone after October 31st.”
He was making changes, from prior notes from the studio. Which sent this movie into the tail spin. The problem wasn't with the initial script, the problems arose when the execs starting putting their grubby little hands over it, to make their own mark here and there.
Crowe, obviously annoyed at this point. Needed re shoots to take all their shitty notes, and add the scenes necessary to make them coherent. Which he was denied.
Pascal then decided to complain about not understanding things, that were altered in their contradicting notes from the studio.
In other words, she is "The bad guy". Studios only see a formula, and a bottom line. They have no idea what it takes to make a movie that isn't outside of their "proven" formula ( See every marvel movie, ever made. They all follow the same formula to a tee.) She then has the gall to put it back on Crowe, because they can't leave well enough alone. It's not crowe's fault, or the scripts fault. It's the notes and amendments made after the fact that are, and they would never had existed without the studio being filled with egotistical ass hats. So at the end of the day, the studios "notes" were asinine, and sent this movie in to the tailspin that eventually ended with an abortion of a movie. If they left well enough alone to begin with, you would have got the movie that they were fawning over when the script was green lit.
TLDR: Let directors actually make the movie they set out to. Studios should be nothing more than distribution and financial backing. Leave the actual writing and directing to those actual people who know what they are doing.
