At least in europe, several of her shows was plagued by bad singing and people getting disa4ppointed, booing and even walking out. I doubt those people-who had been waiting years for this-will pay to see her again, especially since that tour also promised that her voice was in fine form. She supposedly sounded good for some shows but that arguably makes it worse because it becomes almost like a gamble to buy tickets and you might not want to take the chance.

I think it will take her some time/tours to rebuild peoples trust in her and I'm not sure she can do that before it's too late. Maybe she should play smaller venues next time rather than stadiums because if she do the latter, I suspect there will be a lot of empty seats...
