Taboo

The series ran 10 seasons across 112 episodes and has finished, so there is no cliffhanger risk.

Taboo is a documentary television series that premiered in 2002 on the National Geographic Channel. The program is an educational look into "taboo" rituals and traditions practiced in some societies, yet forbidden and illegal in others. Each hour long episode details a specific topic, such as marriage or initiation rituals, and explores how such topics are viewed throughout the world. Taboo generally focuses on the most misunderstood, despised, or disagreed-upon activities, jobs, and roles.
