The next season of TNT’s Kyra Sedgwick series The Closer, its seventh, will also be its last. Sedgwick made the decision herself. The series is currently nearing the end of its sixth season, and averaging about 8 million viewers per episode. The fifteen-episode final season will begin filming in spring 2011, and air later that year. As TV critic Alan Sepinwall pointed out on Twitter, basic cable's not quite the home to full-grown, dope actresses it was just a few years ago.
