Yeah, I emphatically don't agree with Paula or Abby (and have disagreed with Ana on many things, too), but I think I could be friends with all of them in real life. They seemed nice on a personal level. Actually, the same goes for Candace, although something about her made me a little uncomfortable, too... Candace was just not very well-spoken, which is why I didn't include her.
I think it's an UO that I liked Perez. For people who didn't watch, the best comparison I'd make is that she was like Sara in the sense that she would attempt to give an inoffensive middle ground opinion most of the time. I know a lot of people don't like Sara either, but I do. Even if they're just kind of there, it's better to have someone nice and polite around than someone annoying or off-putting. Actually, Rosie Perez had that same "We're a Team" mentality as Sara, trying to smooth over disagreements and bring more camaraderie between the cast. It's unfortunate she had to be on the season she was. :(
