The Glass Castle Movie Trailer vs. Book

Upon first hearing the news that The Glass Castle, a memoir by Jeanette Walls, was being adapted into a movie, I highly doubted that it would be accurate to the movie.

And, after watching it, the suspicion I had just solidified even further. The way they portrayed the dad, Rex Walls, as a very inspiring person, is extremely inaccurate. Rex loved his kids, sure, but he was an alcoholic who wound spend all of their money on prostitutes and, obviously, alcohol. In the trailer, they only showed one part where Jeannette got angry at her dad, but that mostly made him seem like the victim. 

The story also appears to go back and forth between Jeannette's current life, and her memories of childhood- which I think won't be as beneficial as the novel. After her introduction, Jeannette dives right into the story, and keeps you enraptured until the very last breath.

But in the style that they've apparently chosen to use, flashbacks back and forth, breaks the enchanting spell that her story casts.
