I am pleasantly surprised by Amalur. Don't get me wrong, there are a few quirks that rub me the wrong way but ultimately didn't detract from the demo for me. Example being the camera, though that might simply require me getting used to it.
The aesthetic felt very nice, especially in a world where the average fantasy world is embodied by Demon Forge. I think all the comments comparing it to WoW are overblown, and that comparing them to Fable feels more appropriate.
In a number of ways, I'd say the Fable comparison is more appropriate than anything. The fluid change of styles in combat, the three separate skill schools, the aesthetic, ect. I think that if you took some of Fable's core concepts and added in some of the old-school elements of traditional fantasy, you have KoA:R.
As for the story; in the demo at least, it does feel very 'traditional' and generic at first, but keep in mind, we have no more than one quest for the story in the demo. For all we know, later on, it'll become a very unique and interesting story. I think the use of Destinies and Fate in the game are interesting as well.
Overall: Better than expected, eagerly waiting for full game.
