I disagree, it isn't action packed which is what Quentin has become known for, but IMO this is his best/well written film so far.
Pulp Fiction is my favorite QT and where he really established himself, and Reservoir Dogs is also great, I even like Death Proof. Really like it. But I feel, as does Quentin, that he really upped his game for this film. I suppose it depends if you watch a movie for the action pacing, or for overall, how it's composed, written, acted, etc. And it didn't take as skilled a cast as PF, most of these actors were virtually unknown and they carried the film. Impressive to say the least.
