I think the programme about Gemma Collins worked best if, like me, you had never heard of her before. When it started, and she was introduced, I nearly switched off, as I was immediately prejudiced by her overly "made up" appearance. However, I quickly got drawn into the story and also noticed in some parts, she was wearing little or no make up and looked quite ordinary. It impressed me that she was willing to appear on-screen without make up!
The main thing was that the story was fascinating - even if she had just been a random person - not any kind of "celebrity".
