I'm still watching, but there is pretty much only one that I am remotely interested in and that's Danica. I think what I dislike the most about these shows is that it really goes away from the best singer to the best looking guy as most of the votes are for a bunch of delusional women picking their TV boyfriend, not any singer that has a shot at a career.
Not that any singer from The Voice has had a real chance. The only people that have done well with The Voice are the judges, but the TV boyfriend has been an issue on American Idol since Season 5 of American Idol and unfortunately, it's carried over to other shows. While The Voice is supposed to choose all of their singers just by the sound of the singer, once the coaches turn around, it goes back to who will be the most marketable.
Danica is nowhere near "the look," so I don't expect to see her for long.
Like it or not, being marketable is what being a singer is all about but I digress. The vocals should be important as well especially since the show is called the Voice. I think if I had a favorite it would be Matt. He's more non conventionally good looking and his voice has something unique to it so I think he's got the whole package. It shouldn't matter because like you say we're not looking for a date. It just helps when they have both.
