U2 was fantastic, and they really took advantage of the format but Postcards from Earth was awful. They didn’t correct a lot of the video so you’d have things like pillars and objects like trees that were curved. And the cheap tickets are at least $100.
The other problem was that the story, [Spoiler Alert] has an environmentalist theme but it was being told on the world’s largest LED screen in a giant air conditioned death star in the middle of the desert. I found this kind of ironic.
