question:
Review: The movie version of this song is much better. The Mariah/Whitney version is simply just a screaming contest to see who can sing better. I admit the song is beautiful and touching, but it would have been better if one of them sung it instead of it being a competition. Buy the soundtrack and listen to the movie version. It showcases the song in a much better light.
