I don't think it's only Natalie struggling with the 'too good' problem. I was struck that when Len said to Abbey on Saturday that she was amazing considering she'd only been dancing for a few weeks, the people I was watching with's reaction was, 'Oh Please!' They were quite convinced she'd had lots of lessons beforehand. Natalie, Abbey, Ashley and Sophie all started at a level where it is hard for them to show improvement, (Sophie isn't said to be not good at Latin so much as 'going backwards') though all of them as they stay in have the chance to get their personalities across and be liked.
To me it works like this:
if you enter Strictly already able to dance, you'll get high scores, great comments, you aren't risking any real humiliation and you'll be safe for weeks so you have the chance to get your personality across and become popular.
if you enter as a beginner, you risk being bad, being criticised, possibly being laughed at by the nation for how crap you are, you have a possibly short time to get your personality across and really have to hope you are popular enough already to give yourself a few weeks.
But if as a learner, you do improve, a lot, and you can do dances that really matter to people, even if they aren't technically perfect, and you can take on the chin the criticism, etc, you can beat the person who arrived able to dance. To be honest that seems fair to me. It seems fairer to me than if being a learner had no advantages at all.
I don't think there is a 'journey' this year, so I think Natalie has a good chance - good luck to her. Nobody has more than a good chance at this stage because we haven't seen the dancing yet. But if someone of the learners does improve and can get themselves to the final and mean a lot to people, good luck to them too.
