Continuity mistake: During the scene where the main teenage bad guy and his two friends are holding up a convenience store, he gets a phone call from his uncle, about kidnapping the 3 ninjas. His uncle says, "here's the address." But he never actually gives it to him.
Suggested correction: There is an alternate version of this film that shows the address being given and the thugs trying to remember it. This version is currently on Hulu as of this writing.
