I didn't have chances to see many musicals. But, so far, the musicals I saw were quite good. Among them, I like "phantom Of the opera" the most (well, ok, I like the lion king too).
I'm a person without patience. So, I easily get bored when the movie or drama isn't that good, but, for phantom, it is so good that I felt my emotion entirely followed the musical from the beginning to the end. Of course, one of the great success is the musical. It isn't like other operas with high-pitched voice all the time. On the contrary, the songs and music are modern like pop. In Phantom, I like "think of me", "phantom of the opera", "all I ask for is you".
When I was in junior high, I already listened to phantom and tried to memorize the songs. I do think it is a very good musical. If I have the chance, I'd love to see it in broadway (or smaller theater), cuz I saw it in Taiwan stadium in Taipei and this place is too big for a musical.. Well, anyway, to listen to the songs are nice too.
