I liked Cosima, and think she has a great voice but I think Guy, Paulini, or Shannon were more likely to be the more commercial success. I am actually surprised based on the crappy music they gave Guy to release as the winner that he made it as successful as he did - full credit to how talented he actually is that he got through that and did his own stuff.
I don't think Cosima would have won, but I think she could have come second instead of Shannon.
After the show, Guy had a bit of a fight until he had the artistic freedom not to release generic ballads.
Shannon and Paulini peaked early with their first singles, both very good cover versions : in Shannon's case the only good song he ever did.
From there it was all downhill into loutishness or petty crime.
All in all though it was probably the strongest top four on any singing show.
I am actually not surprised with this one. If Alex has to hook up with a guy why not one that looks really effeminate. Even the producers suggested he was possibly trans with the super lame "I was not born Bill....." teaser.
