Django is the best one since Basterds, which was the best one since Pulp. QT's cameo in Django does give me pause, mind you. Nearly ruined the entire operation with that nonsense. but there is so much gold in the rest of the movie, like I can't even think of another scene or performance that wasn't pitch perfect.
The next tier is Hollywood, Jackie Brown, and Reservoir Dogs. Absolute QT magic, but there are times when they sort of sag a bit.
The bottom tier in the mocat QT system are the KB's and H8 (still great! but somehow not quite the same magic for me)
