# Earth: Final Conflict
*Earth: Final Conflict* is an American-Canadian science fiction television series that ran in syndication from 1997 to 2002, produced by Alliance Atlantis Communications and Tribune Entertainment and credited to *Star Trek* creator [Gene Roddenberry](https://www.edgepedia.org/gene-roddenberry), who had died years before the series began development.[1](https://sf-encyclopedia.com/entry/earth_final_conflict) Its premise follows the Taelons, an advanced alien species that arrives on Earth bearing gifts of technology and is welcomed as the "Companions", while a human resistance suspects their true motives.[1](https://sf-encyclopedia.com/entry/earth_final_conflict) The series ran five seasons and 110 one-hour episodes, and was the first of two posthumous Roddenberry projects brought to screen by his widow Majel Barrett Roddenberry, the other being *[Andromeda](https://www.edgepedia.org/andromeda-tv-series)* (2000-2005).[1](https://sf-encyclopedia.com/entry/earth_final_conflict)

## Premise
The series is set early in the 21st century, when the Taelons arrive on Earth on a seemingly peaceful mission to share their knowledge and technology.[7](https://www.primevideo.com/detail/0G03RHF33DYSA0B3IXLVTV3IU4) In exchange for refuge, the Taelons offer access to their advanced technology, and disease, war, and pollution are nearly eliminated.[3](https://www.roddenberry.com/entertainment/) Selected Taelons, called Companions, live among humans and are aided by human agents implanted with a CVI, an alien virus that increases intelligence and carries a "motivational imperative" enforcing loyalty to the Taelons.[1](https://sf-encyclopedia.com/entry/earth_final_conflict) • [8](https://www-users.york.ac.uk/~ss44/sf/tv/earthfc/1r.htm)
**The double agent setup.** A human group suspicious of Taelon motives recruits William Boone, the newly appointed police-captain bodyguard to the North American Companion Da'an (Leni Parker).[1](https://sf-encyclopedia.com/entry/earth_final_conflict) • [7](https://www.primevideo.com/detail/0G03RHF33DYSA0B3IXLVTV3IU4) The resistance disables the loyalty function of Boone's implant, making him a double agent who serves the Companions publicly while investigating them for the resistance.[1](https://sf-encyclopedia.com/entry/earth_final_conflict) A season 1 review praised the moral ambiguity on both sides: the Taelons are portrayed as a conflicted race, some more pro-human than others, and the resistance sometimes appears irrationally fanatic and sometimes as Earth's last hope.[8](https://www-users.york.ac.uk/~ss44/sf/tv/earthfc/1r.htm)
## Production and origins
Roddenberry originally conceived the idea under the title *Battleground: Earth*.[3](https://www.roddenberry.com/entertainment/) • [9](https://earthfinalconflict.fandom.com/wiki/Earth%3A_Final_Conflict) After his death, his widow Majel Barrett Roddenberry found his notes and developed the series from them.[10](https://earthfinalconflict.fandom.com/wiki/Gene_Roddenberry) Producers included Majel Barrett Roddenberry, Paul Gertz, David Kirschner, and Seaton McLean; writers included Gertz, John Whelpley, George Geiger, and D. C. Fontana; directors included Brenton Spencer and [Vincenzo Natali](https://www.edgepedia.org/vincenzo-natali).[1](https://sf-encyclopedia.com/entry/earth_final_conflict) In Canada the series aired on CTV, Fridays at 10:00 pm in the 1997-98 season and moving to Saturdays at 7:00 pm in 1998-99.[11](https://broadcasting-history.ca/earth-final-conflict/)
## Cast changes and retooling
The series was retooled and redirected several times across its five seasons.[1](https://sf-encyclopedia.com/entry/earth_final_conflict) Boone was killed at the end of the first season and replaced as lead by Liam Kincaid, an alien-human hybrid played by Robert Leeshock; Kincaid in turn was replaced in the fifth season by resistance member Renee Palmer, played by Jayne Heitmeyer.[1](https://sf-encyclopedia.com/entry/earth_final_conflict) Other main characters were also frequently replaced; only Von Flores's Ronald Sandoval appeared in all 110 episodes.[1](https://sf-encyclopedia.com/entry/earth_final_conflict) The Taelons themselves were eventually displaced as antagonists by other alien species, and in the fifth season they disappeared entirely in favor of a new villain race, the Atavus.[1](https://sf-encyclopedia.com/entry/earth_final_conflict) • [6](https://www.rottentomatoes.com/tv/earth_final_conflict/s05)
The Science Fiction Encyclopedia judges that this inconsistency, together with what it calls indifferent writing and acting, produced a "centreless work" that, like *Andromeda*, never found the story it wanted to tell.[1](https://sf-encyclopedia.com/entry/earth_final_conflict) Reviewers at the time and since have been kinder to the first season: Den of Geek's Kayti Burt called it "pretty great" while noting the rough recasting and redirection over five seasons, and a contemporary season 1 review rated the show worth watching for its handling of secrets and story arcs.[6](https://www.rottentomatoes.com/tv/earth_final_conflict/s05) • [8](https://www-users.york.ac.uk/~ss44/sf/tv/earthfc/1r.htm)
## Reception and availability
On IMDb the series holds a 6.3/10 rating from about 5,200 users.[4](https://www.imdb.com/title/tt0123816) Rotten Tomatoes shows a 100% Tomatometer for season 1 based on three critic reviews, no critic score for season 2, and 40% for season 5 based on one review; the site's audience average across the series is 60% from fewer than 50 ratings.[5](https://www.rottentomatoes.com/tv/earth_final_conflict/s01) • [6](https://www.rottentomatoes.com/tv/earth_final_conflict/s05) • [2](https://www.rottentomatoes.com/tv/earth_final_conflict) [Space.com](https://www.edgepedia.org/space-com) ranked the series tenth in a 1990s sci-fi television list, crediting its worldbuilding and [Majel Barrett](https://www.edgepedia.org/majel-barrett)-Roddenberry's stewardship while noting that its tonal trajectory wavered in later years.[12](https://www.space.com/entertainment/space-movies-shows/the-10-best-sci-fi-tv-shows-of-the-1990s)
The series remains available: it streams on Amazon Prime Video, Philo, The Roku Channel, Plex, and Tubi, and can be purchased on Fandango at Home, Amazon Video, and the Apple TV Store.[13](https://www.justwatch.com/us/tv-show/earth-final-conflict)
## Spin-off novels
A shared-world book franchise expanded the series. *The First Protector* (2000) by James White is a distant prequel; *Requiem for Boone* (2000) is by Debra Doyle and James D. Macdonald; and *Legacy* (2002) by Glenn R. Sixbury concludes the sequence.[1](https://sf-encyclopedia.com/entry/earth_final_conflict) Fred Saberhagen's *Gene Roddenberry's Earth: Final Conflict: The Arrival* (Tor, December 1999) was the first of a projected series in which each entry came from a different author, dramatizing resistance leader Jonathan Doors's conviction that the Taelons must be subtly thwarted because they are too advanced to confront directly.[14](https://www.kirkusreviews.com/book-reviews/fred-saberhagen/gene-roddenberrys-earth-final-conflict-the-arrival/?page=6)
