I think her performance was good. I think people's expectations of Mariah are unrealistic. She sounds the same she did when she recorded the song. Yes, there is a difference in her singing technique, but she sounds the same. This is the kind of performance people like to see. Know one likes when she tries to act 13 years old, wears k-mart mini dresses, and lip sings. People like Mariah to sing so there is no need to be mean to her for sounding good singing live.
