Oh, Rachel!!!!!
What possessed you to take a role in that schmaltzy crap fest that is 'Brothers and Sisters'? I know you've got to pay the bills but you were up there with Winslet, Kidman, Collette et al in the 90s with excellent performances in diverse roles. Sure you can be forgiven for your foray into TV with the complex, well-written character in Six Feet Under but now you're just Mary-Ellen in 'The Waltons' of the new millennium. Rhonda would be spinning in her wheelchair. Pity.
You can lead a horse to water but a pencil must be lead.
