Continuing with the storyline of the five factions in post-apocalyptic Chicago, Tris’ divergence has been exposed and she’s fleeing alongside the people she cares about most. Other than the numerous conflicts with relationships and the Erudite, Tris’ inner-conflict is the main focus and cause for many of the important events that contribute to the unraveling plot. With many inevitable deaths, determined enemies, and plot twists, she takes it upon herself to protect everyone she cares about, but in doing so, she finds herself in a troubling situation.
Although the fighting scenes appeared too staged at times (like when Four, played by Theo James, is seen throwing a punch at one of the Factionless on a moving train), there was still plenty more action in this movie than the previous one to leave anyone satisfied and hungry for more.
Along with romance, there were many unexpected dramatic moments that just take you by complete surprise, but what was really surprising was the vast improvement in the effects. A major visual effect, which immediately engaged the viewers, was when the buildings were torn apart into numerous pieces. Some of the most incredible visual scenes take place when Tris undergoes the simulations (an aptitude test in which illusions created in a person's mind that are triggered by serum).
Readers of the series might be disappointed with the last part of the film because of the lack of major scenes from the book series, but this issue is common in film adaptations and so can be forgiven (albeit begrudgingly).
