There's way more going on here than just a standard remake or some simple homage to the seventies.
I don't really see it. If this movie actually 'reinvented' the genre, then sure, fine—you could argue it’s genius or that Quentin Tarantino is some massive auteur. But there's zero reinvention happening here.
To me, all this posturing and acting like this is something special when it's basically just an average flick... it's just annoying. And since QT is treated like this 'artsy' filmmaker in the USA—kind of like how people used to view Goddard and his crew back in Europe 🙄—he clearly knows his cinema history, but the guy just lacks any real standards. Everything is gold to him. Everything is great. Well, it isn't. 😛
Kung Fu movies are built on three things: action, action, and more action. Plot and characters? Nowhere to be found. They’re cheap to produce, churned out by the factory, and the profit margins are always huge. There's another genre of films you could describe exactly the same way, and if I recall correctly, it's usually the same crowd watching them. Jesus, why am I even doing this... 😕
