This review may contain spoilers. I can handle the truth.
Early on when they're like "you don't kill the wolf you remove its fangs" I was really sure that would eventually pay off in some metaphorical way in the final battle. Like the 5th brother is about to kill someone but instead he just ties them up and takes their weapon or something. In fact it does pay off in the final battle but it's completely literal lmao he just rips out their teeth. Fucking brutal.
