I saw this last week. I've heard of the book (and musical production), of course, but have never read this classic. I heard wonderful things about the movie, and I knew I wanted to see it.
The movie itself was not my typical cup of tea. While I love musicals, I prefer more contemporary (like Hairspray and Mamma Mia LoL), rather than 18th century, particularly set in a foreign country. That said, the acting was superb, and I found myself loving the songs.
The best part was the beautiful story of redemption. That is something that will stay with me for a long time. It is a long movie, and at times moved a little slowly for me, but it certainly was never what I consider boring. Les Mis offers so much food for thought, is a stunning parallel of Christ's love for us, and I strongly recommend it. I hope this film ends up with a couple of Oscars to add to its name.
