First and foremost, I'd like to say that this film is a masterpiece which millions of people across the world fell in love with. I first saw it in third grade, and I was officially OBSESSED. I love it, and so does my family. However, although The Phantom of the Opera is notably THE most successful musical of all time (not to mention the longest running), a huge lack of teens have heard of it. This fim/musical is something that is not just for theatre geeks. It's about loving someone no matter who they are, and how love can come in many forms. It's also a thriller/mystery, which will interest teens.
This film does contain some things that are questionable. There is a 1 second frame of a man's bare butt, and there's naked statues everywhere. It should be noted that, in regard to the statues, it's what was considered artistic and beautiful. It's no different than a nude painting, really. It's really just for the purpose of historical accuracy. There's kissing, touching, the usual lovey dovey content.
As for violence, a bit of blood after a sword fight, choking, strangling with a noose (the man ends up dead and is dangling from the rafters), and whipping. There is also a deformity on The Phantom's face, but that's from birth.
Swearing constists of damn and hell. But, hell is used only in the proper context, when speaking of 'The Angel in Hell' or 'This loathsome gargoyle who burns in Hell but yearns for Heaven.' There is only one time it is used in a profane manner. 'Who the hell is he?'
Christine is a positive role model, as is Raoul, Madame Giry, and Meg Giry. However, the Phantom is definitely an extremely complex character. He is traumatized and has a very hard time understanding love, as he never really had any. He is extremely possessive and manipulative. At one point where Christine wants to take off his mask, he shoves her to the floor, and calls her a viper, prying Pandora, demon, and a Little Lying Delilah. He goes so far as to have her other love interest tied up in a noose, with him holding the rope to kill him at any moment if she doesn't decide to spend her life with him. He's very toxic, yet has another loving and caring side that comes out around Christine.
Topics to discuss would be the depth of the characters, such as the Phantom and Christine, relationships between characters, how music made the story more powerful, e.t.c.
Overall, the movie is something that anyone over ten could handle. I believe it can be used as educational as well, in music classes and such, because The Phantom of the Opera isn't just a musical/film; it's an experience. It really gets to your heart and keeps you thinking after the screen goes black. This is a must see for everyone!
