I never read the novel, but I do recall enjoying the film. I often read books that I know are going to be made into movies so I can be one of those snobs in the theater, at the end of the film, who exclaims, "the book was so much better." I started The Goldfinch recently, reading a few pages aloud to my wife in bed at night before we fall asleep, but found it a difficult book to read that way for some reason. So, now we're getting into The Woman in the Window.
Maybe you can read The Kite Runner and tell me which is better, the book or the movie. ☺️
