One look at Sisu should be enough for any reasonable to immediately deduce that in no way shape or for show you screw with this guy on any level. Phrases like "Yes, sir No, sir, May I help, sir, Thank you for not forcibly removing my spleen, sir" are all perfectly acceptable forms of communication with Sisu. Things like, "Imma shoot your dog, blow up your horse, steal your gold and burn down your country," are NOT what one would call a sensible conversation. Sisu is a film that flew under the radar for many action fans for the simple reason that a theatrical release shortly after the worst of the COVID pandemic killed the hopes and dreams of most films that weren't named Godzilla or Maverick.  This film is worthy of being in a "Banger" month so please see the film before you listen.
P.S. I know damn well that the main character's name isn't Sisu. Don't @ me. Sisu is way easier to remember than Aatami.
