I just finished watching my video of the final program and I agree with you 100%. Garry & Rita's routine was my favorite of the night!!!
That routine didn't work for me. I almost liked it a few times during the V.Waltz and Q-Step snippets. But, no, didn't like it. I thought it was a little loose and sloppy and trying too hard. I think I felt like they were time and again sacrificing the character of the dances on the altar of the gimmick/music.
I think I was spoiled forever by http://youtube.com/watch?v=0_EXdbsyslg . I was totally enthralled by this routine when I first saw it.
