As for the remainder that went through, I'm not impressed. Those 2 guys with the blackish colored vests should have gone through, especially with the last stunt they did blindfolded. Nope, instead we get singing and dancing.
Sacred Riana just creeps me out and since she already won, she should not be allowed to participate. Again, JMO. I would not pay to see any one of these acts.
I also do not think that the buzzer should still be there for the judges to push since they were chosen at the "get to". Imagine yourself up there competing to get through and in the middle of your routine, a judge pushes it while you're trying to concentrate on what you're doing. It's just wrong IMO; they are already nervous as heck and to hear that would make it much worse.
