TKAM Final Chapters

I would say the author left nothing unsolved.  Bob Ewell got what he deserved in the end, especially after what he tried to do to Scout and Jem.  The identity of Aurthur Radley had been revealed.  Personally, I think the author made him out to be slightly mentally challenged, and this would be the reason he stays inside much of the time.  Either this, or he was just overly socially deprived.

Other people said the book ended poorly, but I think that the author couldn't have ended it better.  Especially when an author only writes one book, it is good to clear up any confusion before finishing.  I don't know what they didn't like about it, but I felt the ending was great.
