The End of a Beautiful Friendship?

Galley Friend B.W. sends us this piece speculating that the good times may be over between QT and the Weinsteins because of Grindhouse.

I have trouble believing that's true, no matter how much I wish it were so. As QT reminded Peter Biskind over and over, he built Miramax, man. He made that studio. Further, while I don't think the Weinsteins the geniuses people make them out to be, I can't imagine they saw Grindhouse as a real commercial prospect. It's a weird, self-involved genre movie--from a genre that only a handful of people have any affection for. Surely they must have seen the project as a reward for QT, a big enough plum to keep him working for them now that they're out on their own again.
