True, sometimes, the movie feels a little too much like another one of those endless comic-book origin stories – yards of exposition, lots of introductions, and then a city-shaking cataclysm for a climax. That's not what the Potter series is about, and with luck, further installments won't follow in the same well-worn commercial path the studio is already running down with its DC friends.
But although it's hard to see how the filmmakers are going to stretch this out for four more promised films, for now fans can at least look forward to this adventure. Harry and Hermione and Ron may have gone on to other things. But some of their most powerful magic is back. And I don't think we could have waited another minute.
