The 12 guys were smokin' hot tonight! (Well, most of them were.)
I didn't get to see the first four performances, but here's what I think of the others.
Robbie Carrico - He projects the rock-star image and has decent vocals. My rating: B
David Archuleta - This guy reminds me of someone I know, but I can't picture who it is. Sweet and likeable, he definitely has the charisma and the stage presence. He's still young, so his vocal range can still change. My rating: A
Danny Noriega - I'd rather not comment on his ambiguous sexuality and effeminate looks, but if he's not confused, then the audience might be. Tonight was the first I saw him perform, and it was mediocre. My rating: C-
Luke Menard - OMFG! It's Orlando Bloom's long-lost brother!

He has a high-pitched voice, and his performance was decent. My rating: B+
Colton Berry - OMFG! It's Ellen DeGeneres' younger brother!

He's got bluesy vocals that are a bit raspy, and he's got this metro/urban style befitting an alternative rock artist. My rating: B
Garrett Hayley - For a young dude who looks a lot like young Leif Garrett, he's certainly got a very laid-back, very subdued personality, quite the opposite of the rock artist image he wants to project. He's still too young and has a boyish pitch, but his performance was all right. My rating: B-
Jason Castro - He's very charismatic and possesses the vocal talent and stage presence. He definitely gets my vote tonight. My rating: A
Michael, the Aussie guy from Atlanta - I honestly don't know what the judges see in him. I'm surprised he even made it to the Top 24. He always sounds like he's struggling with the high notes, and I certainly could've done a much better rendition of Queen's Bohemian Rhapsody at the audition (and that's not saying something). My rating: D
So there you have it!
