I think so far the series is worthwhile, though for me personally it's primarily for the footage. It's also making me realize just how little I really know about how many people were involved in making these places a reality. I thought the second episode did a far more effective job than most pieces of writing at showing how there really was no leadership at the top and the very real effect that had on the parks.
That said, it was definitely weird that Tony Baxter was totally absent from the second episode (with Barry Braverman not only appearing multiple times, but DIRECTLY QUOTING BAXTER). The way it is done comes off as 100% deliberate.
And the second episode continuing to reiterate that the company plainly has no interest in honoring the Magic Kingdom's legacy isn't surprising but is depressing. Despite debuting in Florida, all of the footage for Space Mountain (or at least 90% of it) is from California. The Magic Kingdom apparently only had duplicate rides of what already existed at Disneyland. I'm no fan of the modern day Magic Kingdom or Walt Disney World, but MK deserves some due diligence here for actually trying new things and making a concerted effort to plus everything that existed at Disneyland at that time. Passport2Dreams and other sites have thoroughly convinced me that, as originally constructed, they succeeded brilliantly. That the change has been undone by ineptness and a variety of other factors doesn't mean these improvements never existed or weren't important in the development of Disney's parks. But alas....
Despite the minor rant above, I really do think that this is a great series and I hope it leads to more park-focused media in the future.
