What makes Quentin Tarantino movies unique?

At one point, a character mentions that Cliff Booth was a "war hero." It's possible that Cliff Booth is somehow also Pitt's Lt. Aldo Raine—the timing could put him somewhere in his late 40s. Or more likely that the two men are related to each other. But, if you stick around through the mid-credit scene in OUATIH, Tarantino gives us another fun Easter Egg, connecting his movies together. Rick Dalton appears in an advertisement for Apple Cigarettes, which firmly places OUATIH in the The Realer Than Real Universe.
