I saw this on Christmas Day and absolutely loved it. I'd never seen Les Miserables before, but I knew the basic plot and characters because I've heard the big songs. I know a lot of people didn't like the changes from the stage version, but I've never seen the stage version so I don't know what all the fuss is about.
Other than Russell Crowe, I thought all the performances were amazing. Also, I'm kind of in love with Samantha Barks now.
Having never seen the stage version before I was kind of caught off guard by how relatively small the parts of Fantine, Eponine, Cosette, and Enjolras are.
I have to admit that I started getting pretty bored near the end. Still, I thought this was a damn good movie and I plan to see it a few more times in the theater.
