I was SO looking forward to this movie, but was disappointed because many key points from the book were missing! I think that the things they left out would have clarified and explained a lot of the behaviors of Anna and Ethan. For example, they showed the car crash, but didn't talk about the fact that Anna was stranded for days in that storm, watching her family die (which was the cause of her agoraphobia and PTSD). We kind of saw Anna and Ethan's relationship, but it wasn't really believable. We weren't shown enough of their relationship to understand how Ethan manipulated Anna into trusting him and believing he was the victim. The movie also completely skimmed over the details of the guesswhoanna account, (how it was Ethan on Anna's computer but Anna, being under the influence of the meds and alcohol, thought that she had created and sent the emails to herself).... and the movie didn't even mention Anna's conversation with her online "friend" (who ended up actually being Ethan). Oh, and then there was Bina, Anna's friend..... I could go on and on.
If they had included more details from the book, sure, the movie might have been longer, but it would have made more sense. It definitely would have been a LOT more intense and mind-blowing, like the book was.
