I think a difference here is that, while The Wall has political undertones, and many of them were updated for the recent Wall tour, they were fairly neutral in their message. This tour is more blatant and direct, Trump's imagery during Pigs, for example.
I agree with Kev that most people go to a rock concert to rock out and enjoy an escape for a couple hours. If I went to this show, I would know what I was going to get though, knowing what I know about the artist and this tour. I really wanted to go to this, but funds and other issues came up, but I am not overly disappointed. Dogs and Pigs would have been worth the price of admission, but there isn't anything else in the setlist, or the overall show, that makes me want to buy a ticket.
