My rambling thoughts.
Astro: Pretty good, tries too hard, comes off as being a brat. Not that likable.
Chris Rene: Rough but has some potential, maybe. Won't last much longer.
Marcus Canty: Good. Likeable.
Phillip Lomax (aka Flomax): Sent to die. LA Reid KNEW what kind of singer he was, and seemed to think his Buble/Bruno Mars style was "current" then has him do something totally different.
The Stereo Hogzz: Good. Likable. Nice throwback to late 80s, B2M style groups.
Intensity: A couple of decent singers, and they'll get the Glee/High School Musical-vote, but not great.
The Brewer Boys: Not good.
Lakoda Rayne: Expected them to suck... but were surprisingly good, and somewhat unique.
Dexter: WTF
LeRoy Bell: Smooth, very likable, sounds like Michael Bolton, not sure how marketable though.
Stacy Francis: A little rough, but quite good and likable.
Josh Krajcik: He always looks like he needs a shower, but great voice. And seems like a nice guy.
Simone Battle: Terrible. Bad song.
Tiah Tolliver: She tries too hard and comes off as annoying. Too much crap going on, on stage. Bad song.
Rachel Crow: Cute but the mashup was a mess. Not as good as before.
Drew: WINNER! Talented, good control, unique, is very likable.
Melanie Amaro: Very surprised they rolled out a Whitney song so soon. Usually a bad idea, but she handled most of it really well. Looked nervous, but is talented and likeable.
Also, the production of the show is so terrible. I hate the camera work, hate the announcer, the host is ok sometimes but he's no Brian Dunkleman. The fact that they seemingly hide the lesser singers with stage theatrics is blatantly obvious. At least they got right to the point and eliminated people without a 60 second dramatic drumroll.
As for the judges, Paula isn't half bad. Nicole is really bad. LA Reid is OK. Simon is Simon, and he screwed up with some of his choices, but at least he sorta fixed some of it.
I hope the show gets better once they get into a regular top 12 routine.
