How do you feel about Katie Cassidy playing Dinah in the new Green Arrow tv series?

I am sorry, I have no idea who tht is.  This sounds obnoxious, but I have not much interest in actors and very little in most pop culture. I have a few that have penetrated my shields, but not many.

I am in the pop culture business and I still only know what is going on in that world from twitter and tumblr!
