Isn't there any obligation to finish this story? It's not like its Sex in the City with a different topic each week. This is an unfinished continual story. It would be like J.K. Rowling saying I've decided not to write the final Harry Potter book. People would be very upset to say the least. I just don't think it's right to hook the viewer's into a series like this one and then cancel it. I think HBO should think hard about doing any type of continuing story line in the future. If they can't guarantee they will finish the story then what is the point in starting it? I didn't even bother to start watching the new series Rome. Here today and gone tomorrow should be the new tag line for HBO.
