Well, there are already two reviews that pretty much sum it up and if you've seen the first CLAMP in Wonderland, you know what to expect.
I love the Mokona's journey through all the CLAMP stories. It's funny, nostalgic and dreamy. I especially love the part where Mokona falls in the soup and Kamui pouts. The music is catchy and makes me happy. It all looks great and the ending with the Tsubasa burst is a perfect finish :D
