A leveling off for TNT’s Dallas reboot, which bagged 2.7 million viewers with its third season debut – its smallest start yet. That said, it suffered nowhere nearly as steep a fall as had its Season 2 starter. That season opened with 2.98 million viewers, but it was a 60% plunge compared to the hefty 6.9 million who’d welcomed the return of the Ewings in the less-crowded summer. That Season 2 starter had been a series low for the new Dallas. TNT notes last night’s third-season kickoff matches the new Dallas’ second-season average.
