Rachel Bilson does a good job of being Rachel Bilson.  She chews up the screen whenever she's on, and she makes you smile.  She has a great way of pulling off humor with just her facial expressions, and oh, yeah, she's hot.  Similar to Ringer, I am tuning in for the lead actress, and so far I am intrigued by the show.  Love interest has already been set up (he's engaged, of course, to the set up nemesis) in Scott Porter, aka Jason Street from FNL.  Nancy Travis plays the know-it-all receptionist to the practice offering sage advice.  The mayor is played by the drug dealer dad from FNL.
