Yes, "Alien: Covenant" is a sequel to "Prometheus." It continues the story of the crew exploring the origins of humanity and the dangerous encounters with the alien species. Set in the same universe as the original "Alien" films, "Covenant" follows the crew of the colony ship Covenant as they discover a remote planet that holds dark secrets, including ties to the events of "Prometheus." The film blends themes of creation, existentialism, and horror, further expanding the lore of the Alien franchise.

"Alien: Covenant" was considered a flop for several reasons. Despite a budget of around $97 million, it grossed approximately $240 million worldwide, which was underwhelming for a franchise film. Critics pointed to a convoluted plot, lack of character development, and a departure from the original horror elements that made the first "Alien" films successful. Additionally, its marketing struggles and mixed reviews led to a diminished interest from audiences, contributing to its underperformance compared to expectations for a sequel in the iconic franchise.

"Alien: Covenant," released in 2017, is a science fiction horror film directed by Ridley Scott. It serves as a sequel to "Prometheus" and a prequel to the original "Alien." The film received mixed to positive reviews, praised for its visuals, atmosphere, and performances, particularly Michael Fassbender's dual role. However, some critics felt it struggled with pacing and lacked the tension of earlier installments. Overall, it appeals to fans of the franchise and those who enjoy complex themes of creation and existentialism, though it may not satisfy all viewers.

"Alien: Covenant" is set in the "Alien" franchise timeline after "Prometheus" (2012) and before the original "Alien" (1979). It takes place in 2104, about 11 years after the events of "Prometheus," following the crew of the colony ship Covenant as they search for a habitable planet. Their journey leads them to a remote world, where they encounter the android David, who survived the events of "Prometheus." This film bridges the gap between the prequels and the original series, further exploring the origins of the xenomorphs.
