Troper, welcome to the XXIst century

Travelers is a Sci-Fi television series co-produced by Netflix and Showcase Television for its first two seasons, and Netflix exclusively from the third season onward. It focuses on a team of five time travelers from the future, coming back to change history and avert the apocalyptic timeline in which they live. Through Mental Time Travel, the Travelers jump back and possess people who died in the original timeline, right before the historically recorded time of death; they take over the person's body and identity from that point forward.The focal Traveler team consists of:  MacLaren (Eric McCormack), team leader  Marcy (MacKenzie Porter), team medical specialis  Carly (Nesta Cooper), team tactical specialist Philip (Reilly Dolman), team historianTrevor (Jared Abrahamson), tech specialist

Things appear straightfoward enough at first, with their planned mission being executed just fine (if improvising a little on the way), but as the plot thickens and knowledge of the future grows so does the difficulty in changing it, as well as telling if the changes are for the better.The show is notable for being created by Brad Wright and starring a not-quite Production Posse of several people who worked on Stargate SG-1 and its many spinoffs (the final episode being directed by none other than Amanda Tapping) sharing some of the writers, directors and producers. It is also surprisingly original in its execution of Science Fiction tropes, taking several already seen concepts (many of them already shown in Stargate-verse) and giving them unique new twists, or analyzing them from new perspectives.

It started in 2016, and a second season was greenlit in early February 2017 and began filming in March. Season three (to air exclusively on Netflix) was announced in March 2018. Filming commenced later that year. It was announced in February 2019 that Netflix has cancelled the series; all three seasons remain available on the streaming site.Has a character page that could use some troper love, along with other expansion.This show provides examples ofnote :

Action Girl: Just about every female Traveler, but Carly in particular.
    A.I. Is a Crapshoot: Its not entirely clear how the dice fell but the Director in charge of the Travelers is an advanced AI. It seems mostly benign, but the Faction absolutely hates it and considers it not only a tyrant that has no business telling human beings what to do, but also considers its Grand Plan to be a failure and believes that solutions deviced by human minds would be more effective in averting the apocalypse.note
        An unexpected kind of AI issue happens in Season 3. When the Director uses an AI to briefly make a little girl into a Messenger able to outhack people trying to destroy a nuclear powerplant the kill switch to shut it down when finished fails to work properly. As a result the AI keeps running inside of the girl's brain  Alien Non-Interference Clause: The Travelers have a (somewhat confusing) list of protocols meant to limit the unintentional changes they cause to the timeline  All for Nothing: The finale of Season 3 reveals that thanks to 001, the Traveler program not only fails to prevent the Bad Future but actually causes it to happen ahead of schedule.
