It's pure speculation on what guides other people in how they cast their votes, but I've never known who I was going to vote for before I've seen the show.

And given that the bookies' favourites often don't win, maybe a lot of the voting public do the same.

Bit of a spoiler really -

Show dances are looking interesting:

Just hope the music isn't cocked up!

I think Kristina is very brave she could have done a ballroom show dance but she wont's to show how well Simon as done he has never danced before and I think Simon has come so far to me it is what the show is all about .Good luck Simon and Kristina you are my winner's

The showdance could definitely impact the votes. Some people have their favourites and stick with them, but some voters may judge purely on who does the most enjoyable showdance. Mark is the favourite to go first but he has been the favourite to leave two weeks running. His showdance looks like it could either be fun or be a bit messy. We shall see.

So long as no one has the same idea as Colin and Erin I think they will all do great show dances that play to their strengths. The show dance is why I watch the final

Colin and Erin's legendary WTF showdance is on youtube now
