It was painfully clear that Mariah wasn't singing live! She has the stage presence of a tree. I honestly like alot of Mariah's music, but watching her bring the songs to life is always disappointing. I was bored out of my mind, throughout all of the show. She's just a dull gal! Whitney, Celine, Christina and Jennifer Hudson (who I don't particularly care for) have so much more energy and natural carisma on stage. I haven't seen Whitney lip sync - ever, in my entire life. If she has I'm certain that it wasn't through an entire show. Mariah was a huge stiff mountain that didn't move at all. She should be singing live. There's not any intricate dancing that she entertains her audience with. Janet and Bey, can be excused because they provide alot more excitment. Mariah waves, points her index finger, holds her ear(for what's suppose to be a high note) and fixes her hair ... This is the most action we get when she performs. She's been doing this for 20 years!
