In more detail:
Fern and Artem - I thought this was a very classy routine, charleston can go a bit slapstick which wouldn't have suited Fern but this choreography did. Agree with Bruno that they needed to give it a bit more oomph but overall pretty good.
Sid and Ola - Wrong music, wrong costumes, too much messing around with the guitar and WHERE was the tango? I did wonder if Ola had been inspired by Kristina & Jason's Priscilla tango last year, which was fabulous, but Jason was not only a better dancer than Sid, but really went for it in the non-tango bits of that dance. Sid just looked a bit awkward and embarrassed in the rock god moments, and terrified in the tango part.
Victoria and Brendan - Not quite a return to the poor form of the first dance but definitely worse than last week. I just don't think she was comfortable with the 'sexy' dance and the wardrobe mishap didn't help. Seriously, what is it with the Strictly costume department?!
Jerry and Anton - covered above. Her time to go but she was really let down by her partner IMO.
Dani and Vincent - coming along nicely. A good effort and with a little more work on the footwork I think she will be a contender for QF.
Michael and Natalie - another shocker but huge entertainment value. A bit better than last week I thought, and I love that they seem to be having a really good time together.
Colin and Kristina - I stand by my earier comment that it is too early in the series for AT. He didn't (/couldn't) do any of the scissoring steps and seemed to struggle with the tango posture. I liked the lifts but there were huge chunks of the routine where he stood still and Kristina danced around him. I think he's a better dancer than that.
Michael and Erin - I thought it was pretty good, he seemed to miss a few steps but recovered well and did a decent job with a tough dance. Nice choreography from Erin. Wish the judges would change the record with the camp/not camp thing.
Kimberley and Pasha - very good, lots of dance content and great to watch. They are really starting to gel
Denise and James - the dance was great but long intro and outro. Denise can cope with more, it would have been good to see her dancing for the whole 1 min 40 or whatever it was.
Lisa and Robin - pretty decent effort with one of the most athletic dances but agree with Nemo, she didn't seem to get off the floor enough for a jive. Still one of my favourite couples though!
Nicky and Karen - I think someone must have had a word with Karen about her choreography! A big improvement on last week but I thought Nicky was a bit 'noodly' in the arms - unless that was part of the character?
Louis and Flavia - AMAZING! How that came in second to Denise and James I do not know. This is why I don't like theme nights, I thought there was good salsa content - as much as there could be in the context of that dance - but he gets penalised for the non-salsa bit, whereas Denise can sit on the floor for about 30 seconds of her routine and score higher? Not fair!
