Agree with Mia looking really stiff with her dancing - you can also see it when she runs or attempts to do anything athletic on the family channel. I would think that it is a confidence thing - many teenagers aren't confident/haven't worked out how to move their bodies as they change/grow - but Mia has written a GUIDE to being confident so it can't be that
To me she comes across as faking confidence a lot but anyone watching can see (from her stiffness) that either shes not confident or not comfortable with what shes doing. Maybe nit-picking but her personality is off as well - mentioned many times that if she had friends her own age then she would have been able to develop her personality appropriately. I've been a long-time viewer of FF and in their earlier videos Mia came across as a very confident and put together young girl so something has changed there. I hope its not as someone suggested previously that she was being forced to perform/produce videos against her will.
