It’s a cultural phenomenon that pretty much all novels are better than their movie adaptation. One of the big exeptions to that is Harper Lee’s classic, To Kill a Mockingbird. The book is still considered one of the most famous novels dealing with the civil rights era, along with Uncle Tom and Gone With the Wind. In 1962, it was made into a movie, that, if possible, is even better. The book complety captures the spirit of a young child, and the movie does just as good a job.
Also, there’s not much concern for parents here. A main plot concerns a man that was convicted of raping a younger woman, but that’s all that is discussed, there’s nothing more. One use of n____r, used by a bigot (in the context, ‘you think I don’t know that you’re a n____r lover?), and two or three uses of son of a b___h, but other than that, and some scary scenes, there’s nothing to be worried about in this movie.
Gregory Peck fully deserved the Oscar he won for his amazingly accurate portrayel of Atticus Finch, and I can’t think of a single reason not to see this movie with any child 11 and up.
