A friend caught Enchanted recently, enjoyed it (with only a few qualifications), and had this to say, which I thought was spot-on:

"Amy Adams has always been the real deal to me; she’s like Isla Fisher's way cooler, way more talented, and frankly hotter sister. And I hear she started on Enchanted for pre-recording the songs and animation and everything even before Junebug, which says quite a lot about Disney's eye for talent.”
