I agree, I don't think anyone's given a performance this series that's close enough to perfection to merit a 10. Jill and Darren's jive last year has been the only one to deserve that score, in my opinion. Not even both times either: it was better the first time they did it, although they got perfect scores the second time.
For me, every element of the dance has to be really special to merit the top score. Bruno knew perfectly well that the routine wasn't perfect but he gave them a 10 anyway. It's a shame for Zoe and Ian, because look at the backlash on here. They did really well, and fully deserved 9s in my opinion, but because Bruno gave them a 10 despite their mistakes, there'll be another week of people talking about them being overmarked. Bruno needs to learn that people often react in the opposite way to the judge's opinions - if they think that a celeb is being unfairly criticised, they're more likely to vote for them, and the opposite holds true also. Zoe and Ian may be his favourites, but he could be doing them more harm than good by overdoing it with his praise and marks. I'm not saying he shouldn't be honest, I just think he should be a bit more careful.
