My first reaction was "what the hell is that?" but after getting over the first shock I have to say I understand the whole idea better. I love the "old" Camp Nou so it's hard to think about it changing so dramatically. Still as Xenmate pointed out it has the feeling of the city with Gaudi and all, and it will point out that while Barca is playing in Camp Nou that is the heart of the city at that moment.
I think that when it's ready and I've been to a game and soaked in the atmosphere and presence of it I will learn to love it.
