Really, I do believe that this one should have finished the series. It has a good, fulfilling ending(I don't mind unhappy endings at all, but they should have a point, if nothing else to be tragic. Mostly Harmless most definitely did NOT have a point.), and despite the lack of Zaphod, which I didn't really notice, it's a fun read. Was the Guide ever intended to be more? No! It's got just as much absurdity as the rest, if a bit more sedate and sense-of-wonder-oriented, but that's all right. At least he wrote well for the style, and at least he struck out in a new direction. I don't understand the fans who hate this book. I loved it as a fitting closure(trust me, people! Ignore "Mostly Harmless," or only read it to know what it says. Don't expect much enjoyment, although you might be interested by the scathing indictment of fans.) to a highly enjoyable little set of books.
