The choreography looked like it had pivots in as filler but the rhythm and flow was good. The Samba is Ola's favourite dance, so I reckon that it was a case of how much Samba could she get out of Ash in this week.
Its a difficult dance and men usually find it especially difficult and Ash seemed to. It was a bit of a salvage operation but it was about as good a one as you could hope for.
