Oddly enough, the role of Charlie is still uncast. Robert Wagner did the pilot (not sure if that's what aired this week), and they're currently "in final talks" with Victor Garber to replace him. Which means at the moment, they don't have a Charlie.
I watched the first few minutes, and was so appalled I switched over to Big Bang Theory (which, if you followed those threads last season, you'll know I am highly disillusioned with). I've been waiting for a thread to see if it got any better after the first five minutes.
