It's a rock opera
Of course there's a lot of singing; Andrew Lloyd Weber composed this as a rock opera. Opera is the art of telling a story with music, particularly singing. So of course there will be a lot of singing. This could be irritating to some people, but I really enjoyed this movie. There are some fairly risqué lyrics and implications, but it's nothing that a 13 year old couldn't handle. Eva is an independent woman who wants to help her people, and while she doesn't always do it in the most honorable of ways, she does what she can with what she has. It definitely falls into more than one genre of movie, as it is a romance, a drama, and a musical, but I don't really think that's terrible. All in all, I enjoyed Evita and have recommended it to some of my friends.
