Agree with the comments that a 90 minute set would have suited them better. I left after an hour, when they were padding it out with covers.
I had started watching from the top right (newly opened) section but it quickly became clear to me that the awful sound up there was due to the rear speaker towers not being in sync with the front ones, and being able to hear both. It became really clear that was the case when Axl spoke between songs and you could hear the delayed repeat. Much better sound in the centre, and I actually thought his voice was fine, but the show just hadn't grabbed me. I'm not massively familiar with the material though so that's on me. Great to hear some enjoyed it.
