Can the sons of J.R. and Bobby Ewing attract big ratings like their daddies once did with the original Dallas? On the new TNT series, there’s certainly more family fighting at SouthFork than ever before. The cast includes Josh Henderson, Jesse Metcalfe, Jordana Brewster, Julie Gonzalo, Brenda Strong, Larry Hagman, Linda Gray, and Patrick Duffy.

The TV show ratings are the best way to tell if Dallas will be cancelled or renewed for a second season. The first season of TNT’s Dallas airs Wednesday nights. There are 10 episodes.

The TV series may have debuted on the 13th but it certainly wasn’t an unlucky day for the cast and crew of Dallas. It was the most-watched TV show in its timeslot on both broadcast and cable. It had the best demo number at 9pm and, at 10pm, was tied for first place in the demo with a CSI rerun on CBS — the original Dallas’ network.

Cable ratings are typically released within a day or so of the show’s airing, except for in the case of weekends and holidays. They are sometimes harder to come by so there may be occasional delays or gaps.

What do you think? Do you like the new Dallas TV series? Do you think that it should be cancelled or renewed for season two?
