DWTS: Let's go back (and forward) in time

While I rarely post about Dancing with the Stars, I almost always watch the performances. And for those who enjoy dancing, I suggest watching the second half of Monday's episode if you have not yet. The remaining couples were asked to perform a Latin ballroom routine with an era in mind from the 70s to future. The dances were entertaining and the costumes were hilarious. It was great. (As for who was kicked off: No surprise, but it was Aaron and Karina.) The remaining couples - Mya and Dimitry, Derek and Joanna, Kym and Donnie, and Louis and Kelly - perform next week before the finals the following week. Who do you think should win? And who do you think will win? (Those are two very different questions...)
