I think an extra half hour of music (non Astonishing) would have pleased audiences a bit more.
I don't have an issue with the first US leg of this tour being TA only and nothing else. The band felt like they wanted to promote the album in this way, I think it makes sense to do it as a stand-alone performance, and attendance seemed to be pretty good for the first leg (the show I was at was sold out).
Where I think they made the mistake was doing a second leg without changing anything up, hitting a lot of small markets. The demand just isn't going to be there for that. I could have driven about 2 hours to see them on the second leg and didn't. Usually, I would, but I already saw the show on the first leg, loved it but I'm good. Now if they were playing in my city, I'd probably go to support the band and because I really do like TA a lot, but travel to see the same show again? No thanks. It's already been posted a couple times but it's worth posting again. Even if they just added an encore, something like A Change of Seasons, I'd be in. I'd travel over 2 hours to the middle of nowhere Ohio and see the show again just to see that rarity played.
