I don't tend to like agreeing with James Jordan, but yes, I think Jay looks very promising (though don't want to say a winner at this early stage). To me he looks like he's had some previous dance experience, which I have no problem with if the case. I welcome the fact he can already dance, as I like to watch people dancing. I also like watching people learn frm scratch too, but much prefer the former, and am not ashmed to admit that.
I didn't understand the praise for Peter in the first week as the top male for me was Jay. While Peter can clearly dance in general terms, I didn't really think he was dancing a cha cha to any real visible degree, whereas I thought Jay was actually doing recognisable cha cha steps and moves. I also even pref Anthony's ability to dance his Jive over Peter's attempt, so I'm not going to jump on the Peter train until I feel the dancing direction warrantes.
