I think that there are a lot of people who don't like Phantom which is why they want to see it close. However, they would feel very different if it was a show that they would like. Even if it was clear that a show was going to announce a closing soon because it isn't doing that well at the box office they would still get up in arms if you said a word about it closing.
I think that there is something enffable about Phantom. It has become the nubmer one show with regards to a big Broadway spectical. I feel like the reason why Cats became the longest running show on Broadway was because it was great with the international tourists. The show had next to no plot and it was just all singing and dancing with elaborate sets and costumes and you didn't need a fluent understanding of the english language to enjoy it. I find that Les Miserables and Miss Saigon had the same probmel with regards to the international market. They were very operatic in the way that they were performed and sung through in english. If you didn't have a good understanding of the English laguage then it would have been hard to sit through those shows. Those two did however have long and healthy runs on Broadway. I find that Phantom is a mixture of the two. You don't need to have a full understanding of the english language even though it is mostly sung because there is enough spectical going on in the sets and in the costumes that you can get lost in that and stll have a good night out at the theatre.
With regards to Ann Hathaway and the Phantom move. From what I understand she was offered the role of Christine ( I think looks wise she would have looked better against Patrick Wilso or Gerry Butler.) But, was signed on to to Pricess Diaries II whenver that started filming. She couldn't do Phantom because Phantom and Princess Dairies II started filming at the same time.
