You can't keep a good thing down. 14 years after their last public debacle, the Ewing family is returning to the primetime limelight in the resurrected "Dallas." The show officially went off the air in 1991 after 13 seasons, a miniseries, and a TV-movie. TV-movies reunited the Ewings in 1996 and 1998, proving that fans couldn't get enough drama from Texas' first family of oil. Now they're back again and they've dragged the kids into it.
