One word: gorgeous. It is a very pretty movie no doubt, and I think it does a good job adapting the musical to the big screen. Story-wise it doesn't have much substance (or make much sense), but neither does the musical. The cast is a hit-and-miss. Emmy Rossum is great as Christine, and her voice is very pleasant. Gerard Butler, on the other hand, lacks the vocal talent required for his role as The Phantom even though he oozes sex appeal (or it could be just the mask). The most boring character, however, has gotta be Patrick Wilson's Raoul, who is as lifeless as a bland love interest could be. The action sequences added in the movie are also quite pointless and redundant, and you can tell they are just there to please the male audience, who otherwise would probably have been bored with a romantic musical involving a guy in a mask.
The movie is flawed but gorgeous, sexy and entertaining. If you like the musical, the chances are you'll probably enjoy the movie too. I did.
