Force of the Ninja (1988, USA) C-93m. *½ D: Emmett Alston. Starring Douglas Ivan, Patricia Ball, John Hobson, Douglas Hamanaka. Lame attempt at fashioning an American ninja movie: When the daughter of a Japanese monarch is kidnapped and held for ransom in Arizona, the Asians send a ninja expert to the States to free her and kill the kidnappers. Little action, boring even for ninja fans.
