My take so far ...
Mike seems OK ... liking him more than I thought I would.
Babbatunde. Not really sure yet. I reckon he's gonna bail on every task that he voted for. Came in all 'Billy Big Balls from Tottenham,' and has turned out to be a bit chicken shit. And 'GOD told me not to do it.' Please! 
Sue. I think she seems OK and quite down to earth, but she's coming across as a little bit bossy already.
Jill. Absolutely love her. Absolute queen. Team leader, and feisty, and gives a clear image why women win so much in football and men don't!
Charlene. Again, absolutely love her. She seems sweet, and up for a good laugh.
Chris. I don't like him. Never did. Still don't like him. I think he's slightly miffed that nobody actually mentioned his weight loss. He wants everybody to talk about it, I think. Olivia said 'you look different,' but she might have meant he looks 10 years older. Yet the first thing he said is 'I used to be REALLY FAT!' like he was fishing for compliments. Also, he reminds me of the episode of Friends where Mindy said 'our friend lost all that weight, and it turns out she didn't have a pretty face.'
Scarlette. She seems OK.
Boy George. Yep, he seems okay.
Olivia. Seems OK, pleasant enough so far.
Owen. Seems OK too. Bit vacant, typical pretty boy, fancies himself a bit.
