Maybe. But I've seen a lot of very surprised and satisfied reactions much like my own the last couple days. Also, I'd recommend checking out the Reverseshot review of the film after you've seen it yourself (they're deliberately care-free when it comes to spoilers). I think they hit this one pretty much on the nose.
And maybe I'm just buying into this particular film much more than others because it feeds so directly into my own personal tastes; a Spaghetti Western WW2 Exploitation film, shot very much in a stagey European theatrical mode, with a 'theme and variations' structure and richly layered themes regarding the roles of cinema and authorship within the larger picture. But I do genuinely think it shows some of QT's most assured filmmaking, from the construction of its mise-en-scene to what are maybe his finest-written screenplay and most compelling cast performances to date. I'd be completely shocked if you don't truly love it yourself.
