I wasn't impressed last night, but then again, Disco is not my favorite genre. For the most part, I didn't agree with the judges (except for Lil).
My opinion ranges from "OK" to "eh", even for Adam. What I like about Adam is that if he doesn't like a genre, he completely rearranges the song (like "Ring of Fire" during country week). I thought "If I Can't Have You" was OK, but I prefer to see Adam rock out. OTOH, my favorite performance of his is "Mad World", so go figure.
Everyone else was "eh". Danny was the most fun. I didn't like the Santana-esque "She Works Hard".
I think that even if Adam were to drop out next week (which won't happen, he's too popular), he will still get a recording contract out of this.
