... as it is sometimes called "The Return of the Five Deadly Venoms", this is vintage Shaw Brothers kung fu at it's finest.
Three men show up at a man's house to kill him, only he's not home, so they decide to chop off his wife's legs and hack off his small son's hands. Just then, the father returns home and calmly slaughters the three killers. Unfortunately, his wife perishes from her wounds, but the son survives, and the father sees to it that he is fitted with fully articulated metal hands. After training into adulthood, the son uses his metal-handed kung fu prowess to cripple the grown children of his mother's killers. And all this just in the first fifteen minutes! All of this training and revenge has left the father and son mean and violent. When a traveler makes an impolite comment, they blind him. When the local blacksmith dares speak out, they render him deaf and mute. When a passerby offers help, they chop off his feet! And finally, when a wandering hero promises to avenge these crimes, they defeat him, put his head in a vice, and give him brain damage! The four victims of the original victims band together and travel to a wise old kung fu master who trains them to overcome their handicaps and become The Crippled Avengers! Exciting, colorful and ludicrous in equal measure, this film actually manages to outdo it's more famous predecessor. Highly recommended to fans of the genre and bizarre-cinema buffs. This genre is definitely not up my film alley, but this one I enjoyed.
