I've seen it. It's basically China in 12 minutes. It shows you one famous Chinese attraction after another. I think parts of the old film were used. Bottom line: it's a beautiful movie that will make you go "Wow!" at the end.
The scenery is definitely spectacular, both the nature and the city scenes. In my opinion, it is now the best World Showcase movie, and at 12.5 minutes long, it's not too hard on your feet either.
