ITA that PP is the weakest link. I don't love her or hate her: I don't watch anything because she's in it, but I don't avoid things she's in either. She's definitely outmatched on this show. It's like Barbie goes to DC. She' just doesn't have much range as an actress. Coyote Ugly was about it for her. She's one that probably wouldn't have a career if she didn't look the way she looks.
That being said, I am enjoying the show. Christopher Gorham definitely makes the show for me. There was a second last night - when they were on the train and right after the reveal that they were on the OTHER train - where I thought he could actually see. When he "looked" across the table at her I had looked away for a second and, when I looked up, I couldn't tell if he was actually looking at her. For the entire commercial break I was trying to figure out all the possible scenarios if he really wasn't blind!
