Basically what you're saying is that there was a time in Tarantino's career when he wrote good scripts and now there's the period of time when he just makes stupid action film that look pretty with gimmicky dialogue.

"the later films just supply characters to add to the bodycount."

Yeah, that's lame. You don't spend five minutes introducing a character to them kill him in the next scene.

"He is veering off in constant search of new aesthetics and abandoning the type of writing that established him."

New aesthetics? He's paying homage to other filmmakers! To act like he's doing anything new visually is ridiculous. This film wasn't visually much different from Pulp Fiction; it just had a more filmic backdrop in Nazi-Occupied France.

Giving Tarantino a pass for this is like giving Pacino a pass for his film choices. He went for deep, meaningful films in the past and now he's interested in investigating over-the-top pulpy characters who yell a lot.
