I'm just catching up. My judgy pants are hoiked so high I'm doing myself damage. Love it. 
Early doors opinion...
Christopher (journalist), is going to be interesting, like him.
Pauline (Kylie video/song), is going to be good, doesn't look like she'll take any crap.
Think Mark (yellow jacket), will turn from best friend to back stabber in a heartbeat.
Tamara (23 my arse), needs to rein it in a bit if she wants to convince them she's lovely, faker than a Marc Jacobs bag from the market.
Helen (sex scandal?), will be eaten alive quickly.
Matthew (up in the box), will either slip under the radar or really struggle. Potential walker.
Danielle (Catholic), is all talk and no action, will moan to BB a lot.
Ditto Steven, (millionaire).
Winston (townie wannabe), seems a bit of a dick but probably harmless. Will try pulling playboy woman within the week.
Fully expect to change my opinion on all of them after about two episodes, as happens every year.
Hope they put more older ones in tomorrow to mix it up a bit. It's always been better with a range of ages. I was glad when Pauline showed up.
