My thoughts:

-I think Michele is playing the best game so far. She sits back, doesn't get involved in the drama and everyone likes her. AFAIK, she hasn't made any secret alliances yet, but I think it's smart not to tie yourself to people so early in the game. Ronnie was bitching about her yesterday, but he tries to stir up so much stuff that I don't think anyone believes a word he says anymore, except for Jordan because she's as dumb as a bag of hair.
Russell is also a pretty smart player, actually. I mean, he can spell shotgun! No, really, I think he's playing the mental game better than people think he is, but he's going to be a huge target because everyone is so worried about him physically.

-Laura's pretty good, too. I do think that Laura is a huge fan of the game and she knows what she's talking about. I saw a pre-show interview with her and picked her to win it all in my PTTE just off of that. Her name has been thrown around a few times, but pretty much everyone has had their name mentioned by someone. She and Ronnie both seem like they've watched the feeds and are big fans of the show. For instance, they are the only ones who knew (or admitted to knowing) that the HOH gets a camera every week to take pictures. Everyone else was like Huh? How do you know that?

-Kevin is very boring and he's rarely on the feeds. I don't think he's a target for anyone though, so maybe he's playing it smart. He is very close with Lydia, so that makes me dislike him a little bit. He's definitely not the fabulous, fun guy that he claims to be.

-I don't know what's up with Jordan. She is very flirty with Russell, too. I could see her getting drunk and making out with either or both of them, but I don't know if she'll go all the way to "booger." If I were her, I don't see how I could resist the hotness of Jeff. And she doesn't care about his homophobic slurs because she uses them too! (Really though, I don't think they're homophobic, just ignorant. They haven't said gay people are disgusting and are going to hell, they just say things like "That shirt is so gay." It's still wrong, but I don't think they're malicious about it.)

-Least likeable cast? Hard to say. I've only watched since season 8 and it'd be hard to top Evel Dick. Then again, it's only day 5 of the feeds and I already had to take a break from them because I couldn't stand to see those people today, so...
