All the technical effects are amazing and impressive. The drones are great, and there's an incredible "ripple" effect. My only complaint is that there's zero story. Just a collection of random cool scenes that have a dark side to them. There's very little narration to connect any of the scenes or even tell you what you're looking at. Someone who doesn't know the Harry Potter films is going to have no idea what's going on for most of this show. They did have a lot of surveys going on after the show, so it'll be interesting to see if anything changes. I kinda doubt it, but at least they're asking. The survey was quite detailed (can't give away what it asked, although it was nothing surprising).
