The show was about a roguish Texas hustler juggling two families while wheelin' & dealin' at a big oil company [think modern-day "Dallas"].
"Lone Star" had gotten mixed to good reviews, with TV Guide's Matt Roush telling an NPR audience that it was one of the show's to watch this season.
However, Fox executives didn't do the show any favors with its time slot: Mondays at 9 pm. This put it against two well-established ratings juggernauts: CBS' "Two and a Half Men" and ABC's "Dancing with the Stars". Good luck with that.
Further slicing up the ratings pie were NBC's ultra-hyped "The Event" and ESPN's "Monday Night Football".
Poor promotion and a highly competitive time slot were too much for a new series to overcome.
