Caleb has remained pretty much the same through the whole season for me. Yes, he has a powerful voice and can move on the stage, but that's his schtick and he is "schticking" to it. I think that is what Keith was saying as well, with a bit of sarcastic eyebrow. I see no movement, and it bores. Every week he is the same. I have tried to like him because he probably will be top two however just because you are considered the best of this group, doesn't mean you will make it out there.
Jena is powerful but it's wrong and warbly at times, but somehow everyone fawns over this. Go figure.
Alex is an artist, Caleb is not. That's the way I see those two and I am hoping they make top two and go against each other. Alex has longevity if he keeps going the way he is, Caleb will be a performer at country fairs and maybe in a vegas show.
Jessica had a better night, and probably bought another week, CJ I feel is going home. Sam is just a joy to watch as a young kid having an adventure of his life. He won't win. I wonder though when he leaves if all his votes will go Alex's way and this may boot someone out such as Jena or Caleb as a shocker. Just saying.
Caleb had a chance last night to show his stuff and he didn't. He just "performed" like he is programmed to, and refuses to use the opportunity to go for growth and creativity. That's why Keith said that IMO.
