I don't trust anything out of FOX, but I've held a suspicion for a while that the producers influence the votes.
Am I paranoid? You make the call.
Check out how they keep cutting off to long-shots on Syesha, sometimes quite jarringly (a "sky cam" shot during the big notes finish?), then compare with the long, snuggly close-ups and pan-ins on Carly, who they let draw you into the song (at least as much as she does).
SYESHA MERCADO - The runaway winner last night*
CARLY SMITHSON
*Castro - do you remember it?
Carly - knarly, but well short of the amount of force this song will withstand
Archuletta - top marks for artistry, but short of Syesha's fantastic emotive content [I know they are trying to make him seem older with the jackets, but ... is that what you'd have selected for "Think of me" or something far more classy/elegant?]
Cook - treading that fine line between singer (immitation) and artistry
Brooke - beautifully and memorably photographed for this one, but this song soars with the exquisite timing that seasoned performers have, mostly, so it's beyond her real earnestness to wrestle it down...
