My feelings about Hazel are as follows:
Had she been like she is
now all the way through she'd be a huge fave, but she wasn't. She can be a very nice person and has shown that recently [minus the bitching] but she messed up the BB game BIG time.
But to be fair she never thought she'd be in with a chance. She had different motives. She went in there to promote her business, she said openly that her body IS her business so she did just that, she promoted her body.
It came across slutty.
It might look good in a photo shoot, and is expected in a video such as this

but it doesn't work in a popularity contest, which is essentially what BB is.
As a model she has learned to behave in a certain way for the camera, to project a certain image and she went into the house in 'work mode' [pouting posing, showing her assets] up until Daley got ejected.
Then reality hit and we're seeing a nicer, more un-posed side to her. We're also seeing her not giving a shit about whether she wins, that's because she never went in to win per-se. She wanted to get work from it.
Now that she's still there the prize is in sight she has adapted, to the idea that she's on BB and actually has finally got with the program, she realises that she might win and that she has to be a nice person to do it. Something, she was never anticipating when it began.
I actually think she'll get what she wants from BB, unlike many of the others.
But I do understand the people who still think she's the slutty [sorry to use the word] version of Hazel that we first saw.
