I think the reason so many are cut right away is because we usually get the top 12 or in the last few years (I believe) top 13. The judges have made the choices in the past, but to make a change they are letting America decide.
JMO, but as usual the judges are way over praising and nobody is perfect each time they sing. I like The Voice for that reason and I also don't like all the drama AI continues to show. I didn't even start watching until last night as I knew it would be all about their back stories and showing us the ones that you know would never make it. Lots of different performances last night and to early for me to even say who I thought was good or not. No one blew me away, although I thought the guy they brought back did a wonderful job with singing Dance With My Father. I agree with others about not being sure if he is for AI, but he is very talented.
