I love the play, I love this version of the movie, and I have loved the music since the sixth grade when I sang them in choir.
A disfigured genius, completely out of touch with reality, a beautiful opera singer, and a dashing young noble in a love triangle. What's not to love? The book was very, very strange, although it adapted well to a play version.
The music gets more and more beautiful from beginning to end, and it always makes me cry, usually starting during Christine's Think of Me. My favorite part is at the end, where Christine kisses Erik. *swoons!* I do that every time, and I'm not sure why. It's just an intensely romantic scene for me, even though Erik is insane and threatening to kill everyone in the theater if Christine doesn't marry him. I'm not sure what that says about me.
The Phantom in this movie wasn't quite as strong as he could have been, which was a little disappointing – the Phantom has to be really good, to carry the rest of the movie – but the rest of the cast was stellar. I thought they cast Christine and Raoul well. It's the best film adaptation of the play that I've seen.
