I thought the show "dance" was horrendous too, they ARE hugely talented, dedicated, all the rest of it, but dancing? Not in my book!
During the show last night (before they made their announcement) I said to DH that with Tom knowing he would be in the dance-off, he was actually at a distinct advantage to the other too, he would have had much longer to mentally prepare.
It is possible to that if they had had the dance-off, regardless of who he would have been against, that Lisa or Rachel may have messed up. Not probable though....., and if the judges did what they are supposed to do and dance for who they think is the best dancer just in the dance-off, Tom could have got through - like Lisa vs Austen (although she was better all through Sat night...)
As an asie, I used to work in Disaster Recovery (well, till it became Business Continuity Planning!)
