This isn't a "shit on this director" thread, I'm actually a big fan. Which is why I was a little shocked I can't think of any specific meaning to derive from his films. I had a teacher say once that writing something you have to ask yourself "so what? why am I writing this" but I can't for the life of me think of what the larger message is behind a single one. Jackie Brown maybe is the exception there, Hateful 8 even less likely.
I know not every movie has to be a moral struggle session, but it seems like the pattern is he likes making movies and there isn't anything deeper than that. And not in the Coen brothers way of "there is no message is the message" kind of theme that highlights the absurdity of reality. Quentin leans into the camp as his bread and butter, but he does it well.
Is he literally just a talented homage-machine who obsessively crafts entertaining movies? Are they just high quality pop-corn flicks?
There's that scene in inglorious basterds about the similarities of king kong and the American slave trade. This scene never comes up again and neither king kong nor America's dark history are referred to again. I think this generally summarizes both what Tarantino thinks of allegory in films and the connections that fans will find in film: it's interesting to think about, but ultimately the movie can work independently of any "meaning" found by people who at times overthink it. It's why I would never own a movie by him. I've enjoyed most of his movies to an extent, but rewatching them doesn't usually lead to any more gratification.
