I just watched Phantom of the Opera (for the zillionth time; lol) and I always feel there is a spiritual?

lesson in the plot; you know good triumphs over evil and true love over sensuality/lust. But I was wondering if anyone else (Christian) ever felt REALLY exhilarated whenever he takes her down to his "lair" underground. I think it is the music partly; but I wonder if it is more. Is there something in us that is drawn to the dark side? Of course at the end true love triumphs; but there is also something so thrilling in the dark love that he has for her as well. I think she loved them both and realized that we all have the capacity for good AND evil; but she chose good and that is very much like what we must do as Christians.
