The entire thing seemed like one giant ad for CSI. And I hate CSI. I like The Who. Their stage was cool. The sounded horrible. It got better but I think they amped up the backing track.
Townsend absolutely should have smashed his guitar. That would have been cool.
There was nothing cool about The Who and people should complain about having to see Townsend's gut. THAT is a wardrobe malfunction of the highest order. Yuck.
When 50% of the band is no longer living, I think it is time to stop singing about teenaged angst.
As for who I would have liked to see perform? I don't know...maybe someone who has had a hit in the last decade?
