I gave Les Miserables a 4 instead of a 5 simply because the main character is dated--audiences and readers today no longer trust such simply good-natured protagonists. Considering when it was written, it deserves a five.
I read the abridged version and that was great. Didn't have time this summer to read all that history. I would recommend this for readers who love Charles Dickens, and for those who don't.
