Sari,
I am not sure that anyone is 'getting' at Americans per se, I think what it is is that our dances used to have to stick pretty much to the rules, ie, limited time out of hold, no props etc etc. I have to say I didn't think there was anything wrong with it.
What we have imported from DWTS is the new results show (rubbish) and quite a lot of deviation from 'the rules' whilst dancing. Len in particular used to be very harsh on couples and would dock a point from them if they did a lift etc.
I prefer the Strictly way rather than the DWTS way ...
I live in both US & UK and am currently in US for a while, whilst I religously watch Strictly, I am not fussed whether I see DWTS or not. Perhaps that is because I tend to know the UK celebs whereas I usually only know one or two of the US celebs.
You Strictly guys want to be grateful you don't watch DWTS live here, the amounts of ad breaks would make you want to shoot yourself
