Just read the latest in Gaiman's Sandman series - The Sandman Overture - which tells the story of what happened to Dream before the start of the saga, the prequel to end all prequels, as it were. It sees Gaiman at his most portentous, his most divorced from the stuff of the everyday. That means this is Gaiman at his weakest, in my estimation.
But any Sandman is good Sandman, and if anyone can get away with pretentious portentousness it's our Neil - I suppose because this is so much part of who he is as a writer that there is no actual pretence involved.
And J.H. Williams's artwork is stunning, even for someone whose vision is as limited as mine.
