Most movies about the business of pornography are moralistic films, showing the exploitation that grinds its participants down and steals their souls (to mix a metaphor).
This is not one of those.
As a movie, it's not sure whether the title character is being ruthlessly exploited, or joyously empowered. She's one or the other both or neither.
A lot of peripheral characters and subplots are drawn in, but all are handled perfunctorily. A lot of star power -- Heather Graham, James Franco, Dev Patel -- is wasted in cardboard roles.
Ashley Hinshaw, playing Cherry, is a beautiful actress, and looks a lot like a younger Heather Graham (no coincidence, I'm sure, in terms of their characters). She doesn't display much range here, and her character is not given a chance to grow (which could be the director's fault).
In the end, it's not bad, but there's nothing there. Despite showing the porn industry, it lacks sleaze; and yet you couldn't call it tasteful. Just dull.
