I thought Melissa was great. I agree that her spin was reminiscent of figure skating. I thought the blonde in pink (#98), Mary, and Alexandra looked good in the few clips of them (though I could have gotten those names wrong, I don't usually get to know the girls until a few episodes in).
For the returners from training camp, I like Tessa, but her kicks are bad. I'm glad they didn't even attempt to string her along for training camp. I actually don't think Ashley M looked any better than she did last year, but I like her. Throughout the show, I couldn't put my finger on who she reminds me of, but then it hit - she reminds a little bit of a young Sharon Case (Young and the Restless). As for Vivian, she definitely seemed a bit fake, but based on what and who they showed, she did seem like one of the better candidates there, IMO.
The twins seemed really annoying. I'm glad they didn't make it through.
Where in the episode was the email that posters were referring to earlier? I don't recall seeing it.
Previews for next week - considering how poor Morgan's dancing was last season, she is the last person who should be showing up late. I'm really interested in next week's episode. The first episode always seems like filler to me, so I'm happy to see the veterans back.
