Seriously, I don't like Lacey's choreography... It's seems like Kung Fu... It's clever to incorporate Mark's abilities into the dance, but not for the whole dance.
Louie was cute, but he needs to get better physically. lol. Chelsie is sooo cute!
As for Donny; he was great, but not excellent. The audience are crazy about him... I guess it's the Osmond charm. lol
Aaron -- It seem like he's copying Karina... His move wasn't quite masculine. :S
