Mariah Carey’s Christmas at Rockefeller Center Performance Shows Vocal Struggle [Video]

I grew up listening to Mariah Carey's Christmas music and enjoyed it every year. Yesterday, the iconic singer struggled in her performance at Rockefeller Center. Many people are attacking her but is that fair?

Carey is going through a lot personally with her divorce from Nick Cannon. She's asked to sing perfectly after several years of delivering high performance entertainment. The high notes were a struggle but the rest of the song was on cool.

Are we demanding too much from our celebrities or should entertainers like Mariah call it quits?
