I didn't watch live and have only just seen it on i player, and having read this thread beforehand I thought it was going to be absolutely awful, but it really was not as bad as I had imagined.
Tango is a hard dance to master as it is entirely different in technique to the other ballrom dances, different stance, different hold etc.
I loved the music, but I do love dancing to Gotan Project. The first thing that I saw is Lesleys awful left hand placement, but the biggest problem I had with the whole dance, was Antons choroegraphy.
I rarely critisise a Pro;s choreo but this for me did not work with the dance. Yes it was all authentic Tango which we all love to see but, in my opinion what he did was not phrased to the music. The groups he was dancing did not work with the music that was playing. He could have added in more slows, to accentuate the timing, some dramatic lines and shaping to work with the music. It was a boring routine, just full of quicks and because Lesley does not know how to use her feet well, - you need good floor pressure, she just looked weak and as though he was steering her through the routine. I would have liked her to have worked harder on her posture and stayed our in his right side more with a better head position. That said, difficult to master.
