One of my co-teachers warned me against watching 'Phantom'; in fact, she said it was her personal crusade to discourage people from watching it (or something like that).
I don't think it was as bad as she put it. However, I am willing to concede that I like the musical enough that I probably ignored whatever weaknesses the film had.
One problem I had, though, was the facial expression of the actress who played Christine. Most of the time, it was utterly blank, with her mouth agape. Nothing wrong with her voice, though.
I think I would have liked to have seen Michael Crawford in the movie, but, since he's in his 60s, I guess it would have been too difficult. But, for me, his voice remains the archetypical Phantom.
What I liked about the movie is that, now, I have some visuals to complement the soundtrack. With my imagination, I can gloss over the film's flaws and see the musical in my mind's eye.
