I loved the movie, but Evey’s character was definitely slighted, to say the very least.
Evey was aged up (at the opening of the book she’s only 16), given a somewhat less dismal life, and portrayed as much less bewildered and dependent on V. I’m sure that in doing this they thought they were providing the film with a Stronger Female Character. The problem is that in the book strength is something that Evey gains over the course of the plot, and so the changes end up destroying about half of her character development.
