They should reclassify this as a Superhero movie, because this is literally Tarantino's origin story.
Basically a string of fights held together with the thinnest of narrative connective tissue. Thankfully the fight choreography is excellent and brutal with Scott Adkins crushing it as Boyka. The overactive foley was distracting and the non-Adkins acting was pretty awful, but who cares when the kicks hit this hard? I have no idea why Scott Adkins isn't getting bigger roles...
