I don't warm to Natalie or more particularly I really mean I don't warm to Natalie's dancing.
There, maybe that is a bit more specific, clear wording in case anyone thinks I don't like her personally. I have no reason not to like her, she comes across as a perfectly nice person, who has also coped very well with and come back from injury and illness issues.
Her dances are technically generally good, and while aware of this supposed training she's previously had ( I am not aware of the details ), I maybe give her slightly less credit than others, but it is ultimately not any sort of big issue for me.
On the night though I don't warm to Natalie's dances in an almost indefinable way. I never really have, they don't pull me in or now ever have me really interested in watching like just about everyone else left in. I am sure many of us have dancers we are just waiting to see again and others that we are much less bothered about, that doesn't mean we don't like them.
There are probably ( and I'm almost trying to analyse it as I write ) various things that draw me in to others such as : Sophie just intrigues me, she's a bit quirky and I have enjoyed watching her confidence develop and maybe become less self conscious. Susanna is a slightly older contestant who I have known only for her day job, and I enjoy watching her give it her all, sometimes a bit out there in being deliberately showey, but not in a way that annoys me really. And Abbey, she has seemed more and more as if she is having a ball, especially as she seems to feel and see herself getting better and thus she becomes more confident in a natural, pleasurable way. Then there is Natalie, and I just don't know, there is nothing in particular about her dances or her "journey" in this series that pulls me in and I am never : oh here's Natalie, what will we have this week, in the way that I feel with most others like I have named there.
I have certainly used the phrase "I don't warm to Natalie" and a kind of combination of all of the above is what I mean, but I'd prefer not to write even a fraction of it each time ! I certainly don't dislike her or am I being dishonest in any way. Others may have similar, slightly different or indefinable reasons for using the phrase, and yes some may actually be substituting it for dislike and just wanting rid of the person.
But OP, don't pigeonhole folk or assume you know how they really feel or what they mean, or make more clear that this might apply to some folk. Because if you feel it about everyone using the phrase, I just think that you are very wrong.
