For me, it was the manufactured drama, as another poster said, and the horrible, nonsensical product placement tie-ins (Candy Crush? Yoplait Yogurt? Hallmark cards? Dixie cups? Shopkins toys?). It just robbed the show of any soul.
As far as the finale goes, I would have placed them Sebastian, Hester, Garos. Sebastian was clearly head and shoulders above the other two, but I have to admit I did like Hester's jacket that was just those big furry sleeves held together with the gold chain. I thought that was really fun and innovative.
