Love the menu music on Disc 1. Hope someone can name it!
I enjoyed the main feature, not so much as a history of Disneyland but as a tribute to Walt and what he meant to the people who worked for him. I loved the bit about his use of the word "things." And, no matter how many times I hear it, I love the way he says "waterfall" in that Pirates promo. The flying saucer segment was a joy, too.
However, Disneyland USA and the three World of Color episodes are the best thing about this set. Man, do they look pristine! The World's Fair episode is incredibly entertaining, and it's sure great to have the Golden Horseshoe on disc. The Seasons episode's a lot of fun, too.
About the trivia game: Be sure to play it! Contains some nice footage of the park, asks intelligent questions (mostly) and, best of all, has the best reward system EVER. Really ties into the overall theme of the set.
Whoever came up with the idea of including a ticket book deserves a raise and a promotion.
