I have to chime in and say I haven't big much of a fan of anything Tarantino's done since Pulp Fiction. I've seen all of them out of a sense of hopefulness (though I only watched about a third or half or so of Basterds, in bits here and there), but they've actually been getting worse and worse for me over time. Django was downright excruciating to watch and not in a "This is supposed to be uncomfortable, because that's the director's intention" sort of way. I probably won't bother at all with the next one.
I actually sort of suspect that Tarantino has been secretly making personal fetish movies all along and is just really good at creating plots that give him a very roundabout excuse to, er, indulge himself.
