This week's notable entries include: 30 Rock: Season Six - a show content to keep doing what it does well, and that's quite good enough; The Closer: The Complete Seventh Season - This final season does a great job of wrapping up the series and it ends on a high note before becoming tired and stale; and Boardwalk Empire: The Complete Second Season - this second year pulls together forecefully into a strong, taut, well-crafted show.
