Well, Patrick Lussier, who co-wrote Terminator: Genisys alongside Laeta Kalogridis, has been discussing the movie, and what would have happened had Genisys been a success.
One such attempt was 2015’s Terminator Genisys, which, while hinting at things to come, ended after one movie.
Terminator Genisys follows the first Terminator’s protagonist, Kyle Reese, a soldier in a post-apocalyptic war against Skynet, who is sent from 2029 to 1984 to avert Sarah Connor’s death.
Despite the Terminator franchise now being comprised of six movies, only the first two are spoken of highly, with each movie chasing that same high ever since.
