I'm not entirely sure I'm going to like this whole story telling arc they're shooting for this week. I've never seen them emphasize it before which is why I think it's some different angle they're shooting for. Question is, will the judges love it or will they accuse the couples of going too far from the dance to tell their story (and/or involving any gimmicks as a result). Of course, depending on the couple, the judges will give a pass or rip them a new one. I am in complete agreement that they should stick with just two dance styles a week, and two dance styles that can at least be easily comparable in difficulty.
I will be really irked and thinking along the lines of conspiracy and, while not rigging, heavily producer manipulation if, after this week, they go back to just two dances a week. Last season was the only season where they had more than two dance styles a week. So it's going to look suspicious if they have 3 dance styles this week, and only two the following week, especially since it seems the waltz will benefit Buzz. I feel like they're setting up an Aiden elimination this week. The quick step is probably going to be a lot more challenging for him than the other 2, and since he'll be being compared to Jake, Evan, and Nicole, he'll probably come out in the bottom tier of that group. I also think Kate will probably ditch the dance and play make believe with her paso, and the judges can't criticize Buzz. Those are the only 3 weak links at this point.
Maks has tweeted that he thinks Erin's waltz will be very memorable

At least I have those two. I like other couples this season, but my intense dislike for Kate, Derek and his ringer, plus the way Evan and Chad seem to be heading into thrown under the bus territory is bugging me.
