<Audrey's appeal to me is the subtlety of her performanceWe're going to have to agree to disagree on the actress playing Audrey. What you see as subtlety, I see as listlessness.
Sherry had a real role to play. I never knew what she was scheming. She had pizazz. Same with Dina. (Is she really dead? We never did see her body. I don't trust the 24 writers.)
I don't think Jack has much depth, but at least his character moves the plot forward. Audrey just vegetates in the CTU medical unit, popping up now and again to confront Jack over his Go-To attitude.
Audrey does nothing except listlessly show her angst over her Paul/Jack situation. She's just there. I could care less whether her character sticks around or not. She doesn't feel real to me.
It may be the writing. It may be the actress's skills. Or it may be both. But for me, until something changes, she'll be an annoying blob taking up dialogue time that could be better used by any other character on the show.
I want more Chloe!
Everyone is entitled to my opinion.
