Query: So Long humor - stick with the trilogy!!!

The first book was terrific, the second great, the third good. Now, however, I think Adams has lost his thread. Looking back on the plot, I realize that nothing was accompished exept the introduction of Fenchurch - a desperatly normal characture. If you really want to finish the series than read the book but it is wiser just to remember the first three books. Of course, if you're a fan you're not going to take my advice and read it anyway but remember, I warned you!
