TNT just cancelled "Dallas" after three seasons. The third season (of the revived legendary series) was not set up for success: it was split into two "mini" seasons and aired on Monday night against the likes of "Dancing with the Stars" and "The Big Bang Theory". During this consumer led movement toward DVR and "On Demand" media, a show like "Dallas" could be extremely successful for Netflix. "Dallas" has a long history (beginning in 1978), extremely loyal fans and a worldwide following. 

From Wikipedia:

"Dallas is an American television drama series developed by Cynthia Cidre and produced by Warner Horizon Televisionthat aired on TNT from June 13, 2012 to September 22, 2014. The series was a revival[1] of the prime time televisionsoap opera of the same name that aired on CBS from 1978 to 1991. The series revolved around the Ewings, a wealthy Dallas family in the oil and cattle-ranching industries.

The series brought back several stars of the original series, including Patrick Duffy as Bobby Ewing, Linda Gray as Sue Ellen Ewing, and Larry Hagman as J.R. Ewing. They were joined by the next generation of characters, including Josh Henderson as John Ross Ewing III, the son of J. R. and Sue Ellen Ewing, Jesse Metcalfe as Christopher Ewing, Bobby's adopted son, and Julie Gonzalo as Pamela Rebecca Barnes, the daughter of Cliff Barnes and Afton Cooper.

The series is made for TNT, sister company to Warner Bros. Television, which has owned the original series since its purchase of Lorimar Television (the original show's production company) in 1989. On July 8, 2011, after viewing the completed pilot episode, TNT gave a green light for the series with a 10-episode order,[2][3] which premiered on June 13, 2012.[4] On June 29, 2012, TNT renewed Dallas for a second season consisting of 15 episodes, which premiered on January 28, 2013.[5][6][7] On April 30, 2013, TNT renewed Dallas for a third season consisting of 15 episodes[8][9] that premiered on Monday, February 24, 2014.[10][11] On October 3, 2014, the series was cancelled by TNT after three seasons.[12]"

In some ways, "Dallas" has an equal, if not bigger, following in Europe and the UK. The global appeal of this series is well documented:

In 2007, British comedian Justin Lee Collins went searching for all the stars of Dallas to bring them together for a special reunion party. The show was broadcast at 9 p.m. Sunday, May 27, 2007, on UK television network Channel 4 as part of the Bring Back... series.

After hunting down most of the main cast by any means necessary (e.g., climbing over security fences and ambushing hotels), Collins interviewed them and gained more knowledge about some of the decisions made throughout the show's seasons.

The participants amongst the cast were Larry Hagman, Linda Gray, Patrick Duffy, Ken Kercheval, Charlene Tilton, Susan Howard and Mary Crosby.

He held his own Oil Baron's Ball, where none of the main cast turned up. However, the actor who played baby Christopher (Eric Farlow) attended. Charlene Tilton spoke in an interview in 2011 about the program, which she said was one of her and the cast's worst experiences ever.[citation needed]

On November 8, 2008, a reunion to commemorate the show's 30th anniversary was held at Southfork Ranch in Parker, Texas, reuniting original cast members Larry Hagman, Patrick Duffy, Linda Gray, Ken Kercheval, Steve Kanaly and Charlene Tilton. Other cast members in attendance were Susan Howard, Audrey Landers, Mary Crosby and Sheree J. Wilson.

The front and back lawn of the fictional Ewing family home played host to a massive barbecue filled with people from the Dallas area, across the U.S. and around the world (who paid as much as $1,000) to reminisce and celebrate the series, as well as meeting with cast members.

During the festivities, Kercheval said he was shocked to see the continued support for the show 17 years after it last aired. "I don't understand it," he said. "The staying power. Who knew?"

Linda Gray also fondly remembered her time on the show: "I think it was a special time. It was a time when there weren't a hundred million channels and the Internet and all of the other things that came to existence."[citation needed]

In March 2011, the Texas Theatre in Dallas began showing two episodes of Dallas on the big screen every Sunday; over 100 patrons, some in costume of their favorite characters, appeared at the free screenings every week.

However, the screenings came to an abrupt end in May 2011 after Warner Bros. issued a cease-and-desist against the Texas Theatre for unauthorized showings, citing the fact that those that were involved in the show's production were not getting paid or benefiting from these screenings.[31]

J.R. Ewing's hat, a foremost symbol of the show's inherent "Americanness" that contributed to its hold over audiences on a global scale, is currently held in theSmithsonian's National Museum of American History's collections.[22]

In a popular Forbidden Broadway parody, an actress playing Mary Martin sings the song "Never Never Panned" to the tune of "Never Never Land" from the musicalPeter Pan. One of the lines sung is "you too can be a star, like my son who plays J.R. on Dallas! We're never never panned!"[citation needed]

The series is mentioned in the lyrics of Swedish pop band ABBA's 1982 single "The Day Before You Came". The line sung is: "There's not, I think, a single episode of Dallas that I didn't see"

And...Dallas even helped end the Cold War:

"Dallas and the Cold War[edit]

Dallas is alleged to have helped partially hasten the downfall of the Eastern Bloc country of Romania during the final years of the Cold War.

Romanian President Nicolae Ceaușescu allowed airings of Dallas, one of the few Western shows allowed to be aired in the Communist state during the 1980s. The belief that the show would be seen as anti-capitalistic backfired on the regime as Romanian citizens desired and sought the luxurious lifestyle seen in the show, compared to the despotic situation in Romania at the time. Shortly after the execution of Ceaușescu and his wife on Christmas Day 1989, the pilot episode of Dallas, which had been edited for a sex scene, was one of the first Western Shows aired on the newly liberated Romanian TV.[30]"

The third season ended with Christopher Ewing, the adopted son of Bobby and Pamela Ewing, being killed by a car bomb. There is also a new power struggle for Ewing Global (formerly Ewing Oil and then Ewing Energies) and there is apparently an unknown daughter of the late J.R. Ewing out there. So much was left open-ended, but especially with the murder of Christopher Ewing (part of the series in one form or another since 1981), "Dallas" fans want and need some continuation and closure. 

To the powers that be at Netflix: Please consider picking up the "Dallas" series. With all the wonderful work done with series such as "House of Cards" and "Orange is the New Black", "Dallas" could be completely transformed and renewed like it should be. Many of us are thankful for Netflix picking up the last season of "The Killing"; it was excecuted perfectly. In this spirit, we come to Netflix, the innovative leader in the modern "On Demand" and streaming media movement. Please don't let one of the greatest series in American TV history end this way. The fans of "Dallas" will prove to you that this is a profitable venture. We have always stuck by the series, and we always will.

Thank you,

Fans of "Dallas"
