Stating the obvious, that's quite the song catalog she can draw from and she's amazing performer to deliver those songs.
On a more superficial basis, that was one of the more sparkly (from sequined outfits to sparkler type indoor fireworks) to flat out fire performances (like fireballs being launched across the screen) to upstaging Mickey performances that I've ever seen at a concert.
By that I mean, I always thought that the one on my person firework effect I wanted to do was to be Mickey at the end of Fantasmic with the fireworks gloves. Miranda one upped that (IMO) with sparkler tassels from her jacket.
