TNT's remake of "Dallas" just got some reasonably good news - highest rated new scripted drama of the season. Last night's launch was seen by nearly 7 million viewers - 6.9 million to be exact. And that's over two hours. Certainly some of this has to be laid off to a curiosity factor - or the "Hey Mabel Come and Look - JR's back on TV!!!" effect. But the launch did well among younger viewers too, so that has to be encouraging for TNT and the crew from South Fork.
