i put down The Help atm, for it's so deep i don't really understand some chapters on it. Now, The Casual Vacancy starting to hit my interest, it's really a cool book
I found 'The Help' to be a fairly light read, but that's a very individual thing. The movie is out on DVD and is fairly close to the book. It deviates some, but is still very good. Why not rent the DVD if you are having trouble with the book.
