I've never seen Les Miserables on stage, and really most of my knowledge of it comes from the DS9 episode where Eddington compares Sisko to Javert. I really wanted to like this movie, but I just couldn't. The story was dull. The music, I Dreamed a Dream aside, was completely unmemorable. The cinematography was ugly as hell. Everything was poorly lit, and there was not a single image that made any kind of impact. The two camera angles have been mentioned already, but man did that drive me nuts. On the plus side, the performances were pretty uniformly good, even if half of the song lyrics were completely lost to a really flat sound mix. Everything just seemed to lack any gravitas.
Also, I'm kind of in love with Samantha Barks now.
You'll have to fight me for her. Damn!
