This period drama takes place at the start of a cultural revolution but is set somewhere that was slow to adapt: a newsroom. This story follows a group of young journalists at a magazine who fight for equality. Among the fighters? A young Nora Ephron, played by guest star Grace Grummer.    Yes, guest star -- meaning the show dropped a familiar name but perhaps doesn't plan on following through with her story. Confusing.    You've seen this sort of thing before, but the characters are appealing enough to make you want more. (Anna Camp's Jane is a particularly bright spot.)    The biggest hurdle for this show will be making viewers forget that Mad Men just finished stomping very similar ground. If the show can set itself apart, though, it could be a satisfying ride.
