"Terminator Genisys" flopped due to several factors, including a convoluted plot that confused audiences and failed to resonate with fans of the original franchise. The film's reliance on nostalgia and time travel mechanics alienated some viewers, while mixed reviews highlighted its lack of originality and depth. Additionally, it faced fierce competition from other summer blockbusters and struggled to establish a new narrative direction for the franchise. Overall, it did not meet box office expectations, leading to disappointing returns.

"Terminator Genisys" serves as a reboot and reimagining of the original "Terminator" series. The film explores an alternate timeline where characters like Sarah Connor and a reprogrammed Terminator (Pops) fight against Skynet's plans. The central point is to prevent the creation of Skynet and the rise of a dystopian future. It blends action, time travel, and themes of fate versus free will, ultimately aiming to redefine the legacy of the franchise while introducing new elements and characters.

"Terminator Genisys" received bad reviews for several reasons, including a convoluted plot that confused both fans and newcomers to the franchise. Critics noted that the film relied heavily on nostalgia while failing to bring fresh ideas, leading to a sense of predictability. The character development was seen as lacking, and the film's attempts at humor often fell flat. Additionally, the special effects and action sequences, while visually impressive, did not compensate for the overall weak script and inconsistent tone, resulting in disappointment among audiences and critics alike.

"Terminator Genisys" (2015) alters the established timeline of the "Terminator" franchise. It introduces a parallel timeline where events diverge from the original series. The film begins in 1984, following the events of the first movie, but quickly shifts to a new timeline where Sarah Connor is raised by a reprogrammed Terminator, known as "Pops." The narrative incorporates time travel, with characters traveling between the past and future, ultimately aiming to prevent the rise of Skynet and the apocalyptic future. This creates an alternate reality distinct from previous films.
