The Divergent series failed to achieve the same commercial success and critical acclaim as its predecessor, the Hunger Games saga, and there are some reasons why. Divergent follows Shailene Woodley's Beatrice "Tris" Prior, the counterpart of Jennifer Lawrence's Katniss Everdeen, in a society where people are divided into factions based on core personality traits. The Divergent books by Veronica Roth closely followed The Hunger Games taking off and were initially very popular among fans of the previous series, but the movies never reached their full potential.
