This is the third classic Hong Kong martial arts movie I've watched in the last few days, and it dawned on me I'd been taking something for granted: no stunt doubles. It seems obvious now, but it's always cool when the actors are genuinely doing all their own stunts, and there's no awkward editing to hide switch-ups between actor and stunt double.
Crippled Avengers proved to be another satisfying martial arts film. It at first seems to centre on a father whose wife is killed and his son maimed by getting his arms chopped off, and their desire for revenge (the son gets metal arms built for him that make his punches super deadly). But no - these two are the villains, and either they were evil all along, or the tragedy made them evil, because they go on to maim another four characters in various ways, and they're the heroes who train for the purpose of seeking revenge for their permanent injuries.
The first third is the weakest - it's all the set-up and main characters getting injured/disfigured one by one. The second third is focused on training, and I think I enjoyed that part the most. And then the final third is where most of the action/revenge is, and it was also largely satisfying, with plenty of impressive choreography and creative fight scenarios on display.
Like many martial arts movies, the ending feels abrupt. I think the first act is a little repetitive, and the way the writers keep finding reasons to send the hero with metal legs out of the action (he's the most powerful, because he had his legs cut off and replaced with iron, much like the main villain's son's arms) gets pretty comical. But most of it works well, and I did find the story and characters more engaging than I usually do in martial arts movies. I think it's pretty successful overall.
