My goodwill toward the books is powered, at this point, by fumes -- ghosts of the full tank of goodwill that the first book provided.
I do think that Severus Snape is the most interesting character in the books, but somehow that strikes me as one of the flaws of the series. I certainly don't understand the whole Snape phenomenon, unless it is being fed by a bunch of women who can't separate Snape from Alan Rickman and Alan Rickman from Colonel Brandon. Maybe we should call him Colonel Snape.
Then there's Dumbledore. I won't get into any "spoilers" here, but the development of Dumbledore's character seems to have followed the same arc as that of the Jedi Knights. Both Dumbledore and the Jedi seem to peter out over the course of the stories. They begin in wisdom and grandeur, and end in ineffectual gestures and a blindness to evil and danger that is so complete as to seem just plain stupid. I realize that this take on Dumbledore relies on a completely straightforward interpretation of the events of Harry Potter and the Half-Blood Prince, and that's one reason that I'm in the all-is-not-as-it-seems camp, but I can't bring myself to care very much whether all is as it seems or not.
I want to care. I want to be out among the crowds waiting at the docks for the arrival of the last installment of Harry Potter. I want to shout up to the Captain, with real feeling, "Is Harry Potter dead?" I want to care about the reply.
As things stand, however, I will linger at the edge of the crowd, wondering whether it is a dearth of taste, or joy, or humanity, that prevents me from mingling among them.
