Dallas (7 and 9:01 p.m., TNT) returns for its third season - its 17th season, if you include the original 14-year run - and its first without J.R. Ewing.The man who played J.R., Larry Hagman, passed away during production of Season 2/Season 16, but his presence loomed large even in the episodes that were produced after his death. And J.R. Is gone but certainly not forgotten now.There aren't many people out there who are bigger "Dallas" fans than I am. And, after seeing the first two episodes of this season, I'm still engaged. I stll want to know what happens next.It's not perfect. The introduction of a new villain isn't altogether smooth, and there's a twist involving one of the returning characters that is, well, pretty crazy. But then there have always been crazy plot twists on "Dallas."It's still fun to watch. And that's what it's supposed to be.Also on TNT, the cable channel introduces Private Lives of Nashville Wives at 8:01 and 10:02 p.m. It's a reality show about unlikable people trying to make it big in country music, and it's pretty much unbearable.And over on NBC, there's a new late night host.
