I'm kind of bored with this season, and I agree with most of the comments already posted. So instead I'll comment on who we saw in the audience:
Erin!!! YAY! I noticed Brandy ran over and hugged her at the end of the dance.
Melanie Griffith sitting next to Jamie Lee Curtis. And did you notice Jamie's reaction when they took Derek/Jennifer out of the marathon dance before Maks/Brandy? She looked surprised to me.
The high point of the night for me was seeing Gilles and Cheryl's dance again!
