The die-hards will think it the right choice, an inspired choice, of course the paso was quite clearly the dance of the series.
He may well win and then it will be lauded as a great decision by them both, when really they will be voting no matter what, as someone said, they could do the hokey kokey!
But for a general viewer, even ones who have favoured him, it is a bad choice.
Firstly the excuses, he is too nervous to do it, it will in some way tarnish it, both make little sense.
In all cases, people do the dance that has been epic for them in the series, mostly because people stop them on the street and say 'oh, that jive', and it is a sort of thank you to them and to celebrate how great it was.
People have been presuming it would be the jive he would do for this very reason.
For most people it will be an obvious omission in the final.
