Then I decided to go back to the world showcase and watch the two circle vision films at Canada and China. I think the China one was the same one I used to watch as a child at Disneyland before Buzz light-year.
Great trip report. As far as the China film you are close it is a updated version of what you saw at DL years ago, but not all the same.
Since I am used to Disneyland and know it like the back of my hand the Magic Kingdom was like déjà vu. Kinda weird, both familiar and unfamiliar at the same time.
I had exactly the same response when I first visited WDW in 1979. I'd grown up at DL, and it was so odd to see the layout generally the same, but the specifics being different. And Liberty Square just blew my mind - I got lost every time I went through there!
Glad you had a great trip. Thanks for the TR, and welcome to Micechat!
