Don't let my 2-star rating for "Mostly Harmless" fool you---I miss Douglas Adams very much. He was a brilliantly funny author, and I'm a huge fan of his first four "Hitchhiker's Guide To The Galaxy" books, his pair of "Dirk Gently" books, and his writing for the "Doctor Who" TV series. But sadly, I must confess, I'm not a fan of Adams' final "Hitchhiker's" book, "Mostly Harmless." The reason is simple: the fifth book, in my opinion, is totally unnecessary. Adams originally intended for the fourth book, "So Long And Thanks For All The Fish," to be the definitive final book in the "Hitchhiker's" saga. There's a *reason* why the fourth book has a farewell title to it, folks! And, like the three books that came before it, I totally loved it---I read the entire "So Long And Thanks..." book in a single day, and I thought that it was a marvelous "conclusion" to the adventures of Arthur Dent & company.Then along came "Mostly Harmless," which, by Adams' own admission, he only wrote on a whim---just for fun, in other words. He came up with a way to extend the series for one more book, which I'm sure delighted some "Hitchhiker's" fans, but I, personally, was so disappointed with the direction of it. Arthur's ladylove, Fenchurch, is gone, and now it turns out that he & Trillian had a daughter (though not by natural means), and that's just for starters. Oh, Adams' writing is still sharp, but despite a very humourous adventure with Ford Prefect & a companion robot toward the beginning, the fifth book, to my dismay, turns surprisingly serious. What can I say---this is simply not how I wanted the "Hitchhiker's" saga to end.I have on my bookshelf a "complete" hardcover edition of "The Hitchhiker's Guide To The Galaxy" that only goes up through "So Long And Thanks For All The Fish." That's fine with me. To me, "So Long" IS the definitive ending of the series. I just don't feel it was necessary for Douglas Adams to extend the story any further. Don't get me wrong, I greatly mourn the man, and I will always treasure his other works of genius, but "Mostly Harmless," for me, came up short. My advice: read the "Hitchhiker's" series through book four ONLY, and you will get a much more satisfying conclusion. But the misstep that is "Mostly Harmless" takes nothing away from the man's great literary gifts---and great laughs---that he gave us throughout his incredible writing career. So long, Douglas, and thanks for all the fish.
