I liked the side by sides, too! I think it helps the stars to see a pro of the same sex do the part they'l lbe doing so they can mirror their moves. A pro can explain how to do a move multiple times but to see it in action and then copy it yourself is the best instruction. Most of the stars did a great job this week.
I'm a Tristan fan, too. I hope some season he gets a good star so he can have a crack at his team getting the mirror ball trophy.
