YMMV / The Octagon

• Complete Monster: Seikura is the resentful half-brother of Scott James and the leader of a powerful, multinational terrorist syndicate. Training aspiring terrorists in the way of the ninja to become assassins and dispersing graduates to commit terrorist actions worldwide, Seikura holds his disciples to a code that, if broken, ensures the death of both them and their entire families. Seikura proves his ruthlessness when he has Nancy, her diplomat brother, and her family—among them a child—all slaughtered by his assassins. Seikura later captures Scott's friend AJ and forces Scott to participate in the titular lethal fighting course, and defiantly slits AJ's throat anyways when Scott passes the test.
• Hilarious in Hindsight: Most of the people in the film don't know what a ninja is and think it's some kind of Japanese technology. Today, ninja is one of the most well-known words, probably because of the popularity of this kind of films.
