I think people voted for Kevin. I voted for Kevin although I like Stacey's documentary work very much and have done for a long time, and was very pleased to see her win.
No, perhaps as a couple they were not technically the best but they were competing against people who were actually professional dancers. Putting Faye and Ashley into Strictly is like putting Sinead Kerr into Dancing On Ice and then complaining the public are not giving her her dues. (Big fan of Sinead and John so that's not a knock on them!!)
It's an entertainment programme, in the end. If you want a seriously judged competition, the big dancesport federations put pretty much all the competition footage up on Youtube. I watch nearly all of that and enjoy it very much.
Also, Joe and Dianne make an adorable (official) couple. So all worked out okay in the end!!
