Whats its about?
Read the book and you'll know, It's only 1700 pages.
Seriously it's regarded by many as one of (if not the) greatest novel ever written. I have a list of about 10 novels that I believe EVERYONE should read. Les Miserables is probably #2 or 3 on that list.
I guess it looks like I'm the only one here looking forward to this film. It remains to be seen how strong the singing will be, Anne Hathaway sounds good in the trailer, but I've never heard Jackman sing, and Russel Crowe I think of as more of a rocker. I'm sure most of the singing won't be as technically perfect as the London, or Broadway stage shows, but I think with the full on movie backdrop that won't really matter so much.
