The movie was really good compared to the book. But I did find some things wrong with the movie.
In the book, Isaac is blond but then in the movie he is a brunet.
And the scene in the book where Isaac is braking Gus's trophies, Hazel wears a dress but in the movie she wears a t-shirt and some jeans. Now I know that is not a big difference but it is something that I noticed. In the book she makes this big deal about how she is going to wear a dress. Okay, it might not have been that big of a deal, but she made a least a little bit of a deal about it.
When Hazel and Gus go to see Peter Van Houten, at the end when Hazel yells at Peter in the book she just yells at him, but in the movie she swears at him.
I think that is it. If I missed anything comment.
Don't forget to be awesome,
Hazel.
