However, I have disagree that DH2 has much of chance at a nomination. For one thing, though it is one of the best-reviewed films of the year so far (it tops my list), it hasn't necessarily had much competition. With the fall bringing more traditional Oscar-bait projects (not mention promising-sounding), DH2 will likely be forgotten by many voters. For another, in the new system you absolutely must have number-one votes, and DH2 is not a film that will top many lists. Sure, we may remember it as one of the year's best, but will it be among THE best? Of course, this is early speculation, but I just don't see it lasting through the grueling Oscar season.
There's also the matter of the fact that none of the other Potter films have been nominated for Best Picture. Last year, Toy Story 3 became the first part-three of a series to be nominated without the other entries doing so; that's the latest in a series to be nominated. HP2 is part eight. In fact, the Potter franchise has only racked up nine nominations TOTAL, with no wins. Three of those nominations were for Stuart Craig and Stephanie McMillan's art direction, and two for John William's scores. The franchise has no nominations in acting, writing, directing, editing, or, obviously, picture. That history is going to be a tall task to overcome.
So what do I make of this "honoring the series" bit? I think that DH2 will earn a handful more nominations than usual, particularly for Visual Effects, Sound Editing/Mixing, and perhaps even Cinematography (it deserves a nomination there), and perhaps even the series only win, for Art Direction; they really like Stuart Craig, so that seems most likely, to say nothing of the genuinely impressive work he and McMillan did in destroying Hogwarts. But a Best Picture nomination? I wouldn't rule it out completely, but I'd say at this point it looks extremely unlikely.
