The "Divergent" series consists of three main films: "Divergent" (2014), "Insurgent" (2015), and "Allegiant" (2016). The series is based on the book trilogy by Veronica Roth. While "Allegiant" was intended to be split into two films, the final installment was ultimately canceled due to poor box office performance, leaving the story unresolved in film format. Therefore, there are only three movies in the series.

"Insurgent," the second film in the Divergent series, continues the story of Tris Prior as she navigates a dystopian society divided into factions. The film features action-packed sequences, strong performances, particularly by Shailene Woodley and Theo James, and explores themes of identity and choice. While it may appeal to fans of the book series and young adult dystopian genres, some viewers find it less compelling than the first film. If you enjoy action and character-driven stories in a futuristic setting, it may be worth watching.

"Divergent 4," originally planned as the concluding film in the "Divergent" series, was canceled primarily due to the poor box office performance of "Allegiant," the third installment. The film did not meet financial expectations, leading to a shift in focus for the studio. Additionally, there were difficulties in securing the original cast for a fourth film, which contributed to the decision. Instead, the franchise shifted towards a potential television adaptation, but as of now, no new developments have been confirmed.

"Divergent," released in 2014, was a commercial success, grossing over $288 million worldwide against a budget of approximately $85 million. It received mixed reviews from critics but garnered a strong fanbase, leading to the production of sequels, including "Insurgent." While it was not universally acclaimed, its box office performance marked it as a hit, contributing to the popularity of the young adult dystopian genre at the time.
