I am a poor sap that flew to SD a few years ago to see what I heard was an Evita-like experience. It was not. Just watched it on Netflix to see if they made any changes since their La Jolla run, I didn't see anything major, though not much of the show/songs were memorable (aside from Pretty Pretty Girl, and F@ck me dress). I did notice the changed the beginning of the show. In La Jolla, it started with the Royal Wedding (using a different actress under the veil), and then Diana steps on stage and comments on the moment (something like "at that exact moment, I was thinking, 'what am I doing here?'
". I wish they had some more of that, because the story plainly told is so boring. This show needed some sort of device - the story told through the tapes she recorded for the book, or framed around her dresses. I am also not sure if they had the palace in the background at La Jolla. I believe it was just the gates and a black/dark background. Good watch for free, but not Broadway caliber.
