Good show. I quite enjoyed it. It did deviate from the book quite a bit, but I've never been one who considered the original to be the inerrant pinnacle of humor. I was rather happy that they didn't stick with a couple of Adams' less funny subplots. I liked the Vogons a lot.
Ya know, I've got a hardcover Hitchhiker's Guide signed by the author. I'm saving it for another 18 years so I can use it to help pay Maggie's college fund.
