I'm pretty neutral on Heidi and Alyssa. All Stars has a much lighter (read: less bitchy) tone than normal PR seasons, mainly because these people have already lived the TV experience and thus, aren't hamming it up as much. Well, except Jay. What a drama kween.
I don't like Zanna from her vibes - despite the fact she says nothing of any noticeable importance, she's there because she wants to be there. She comes off to me as a bit pinched and narrow, like she has tunnel vision when it comes to fashion and people. Not in a conservative sense, but more or less like those annoying people who love modern art/dance/music and refuse to believe it's hideous and a bit deforming to the human condition. They'll stand up for hours explaining to you that this BLANK canvas with its singular RED dot is an expression of FEAR and doubt in the midst of the emptiness that is MODERN MAN. It's not to say that is not true, but it is most certainly not the best or most beautiful way to represent an idea.
