It won't take very long in your viewing of "Kill Or Be Killed" to start experiencing a severe case of deja-vu. Even if you can't recall exactly which westerns you saw these elements before, you will know that you have seen them before. A single woman struggling to keep a hold of her land while an evil rival rancher is trying to push her and her family away so he can have the land? A lone gunfighter coming into town who has the courage to stand up to the evil rival rancher and his followers? Viewers who know their spaghetti westerns well will recognize the part of the movie where the heroic gunfighter is beat up and left for dead (and is subsequently rescued by a grizzled old coot) is derived from "A Fistful Of Dollars". Still, as unoriginal as this western might be, it is competently done, zipping by at a good clip and seldom having any dead spots. There is also a pretty good musical score by Carlo Rusticelli. So if you are a western fan who doesn't mind seeing the same things over again, this movie is probably a safe bet.
