"Impulse" is a must see for any fan of B moviedom! During a low point in his career, Shatner gives a stellar performance as Matt a psychotic killer. He begins his killing ways as a child when he sees his mother, in their home, being raped by a soldier (played by William Kerwin) and plunges a Samurai sword into him. The film then flashes forward to 1974 Florida where he kills his current lover, then comes into a small town and wins the heart of a widow, but not her disapproving young daughter. The daughter is wise to his motives after she witnesses Shatner kill Harold Sakata in a car wash, but no one will believe her until the bloody climax of the film. Think Shatner's acting was tacky in his Star Trek hey day? He goes over the top in this cheapy thriller. And yes, dig his groovy duds! Everything from polyester zig zag print shirts to striped tank top and white pimp suit complete with hat! Cheesy scenes, dialogue and plot make this drive in delight a movie to seek out. Hard to find, it is slowly making it's way to DVD. This would have made an excellent MST3K episode! Fun for all!
