Ninja: Silent Assassin is a Hong Kong-produced martial arts action movie released in 1987.
In the build-up to the final battle, there is a lot of loud-speaking almost like yelling, teeth-gnashing and the characters saying, "To the death!" stupidly. The acting is amateurish and any attempt at seriousness is thrashed when they all appear in their ninja costumes. They all looked like clowns playing as ninjas. The music and sound effects are horribly funny too.
