"People seem to not like the Phantom of the opera Movie, but I'm not sure why."
For one, they oversexualized the title character. By taking your deformed villain and turning his crippling deformity into a mere rashy sunburn...thing just for the sake of making him more physically attractive to the tween girls who are seeing the movie, you completely miss the point of the ENTIRE story. Also, while his acting was decent, Gerard Butler's rock-styled singing was just not cut out for the role. If they really wanted him in the part, they should have just dubbed in someone else's voice.
Also, Emmy Rossum as Christine. I understand that they wanted a young, teenage girl for the role, but Rossum was just too young at the time; her voice was not strong enough, and her acting back then was sub-par at best. Had they made the movie with her a good five or ten years later, she could have done the part justice, but at the time she just wasn't right for the role. (Christine is supposed to be an opera singer, of which Rossum did not have the pipes to convince me with yet.)
The rest of the cast was decent, so I'll continue on to the other topic: Oversexualizing. Yes, the stage show has sensual themes throughout the story, but they are very subtle, and they are intertwined with a slightly gothic feel and an air of mystery surrounding the Phantom. However, the movie throws these other components completely out the window and bulks up on the sexiness, which is a HUGE thing that makes many fans of the musical groan and roll their eyes. The lair itself was very disappointing, as I felt like I was looking at some sort of sex chamber designed for a porno Dracula movie. (The place was too lit up. They should have designed it closer to the way it looks onstage.) On a random note, showing and explaining how the Phantom does his tricks (i.e. Carlotta's croaking) was a bad idea, because part of the fun of Phantom of the Opera is watching the Phantom screw around with everyone and wondering how he manages to pull off such bizarre acts of magic. Also, the sword fight was just STUPID and not needed at all.
The cinematography was gorgeous, and there were a few things that worked, but overall the movie was just not up to par with what many fans were expecting. I could argue that the 2004 Phantom film is one of the absolute worst musical-to-movie adaptations out there; the musical would do well to have a movie remake in the next ten to twenty years.
