Douglas Adams' The Hitchhiker's Guide to the Galaxy is brilliant comedy, but one really has to start with the book (or with one of the radio plays) in order to be able to appreciate it.
Actually, Adams wrote the whole series originally as a radio series and it started in March 1978 on BBC Radio 4. After the success of the radio series he was asked to write a book from the story. The Hitchhiker’s Guide to the Galaxy was first published in England in September 1979 and immediately became a best-seller. This does not happen very often to new authors, but it is perfectly understandable if you know the radio plays.
I have just seen the movie based on The Hitchhiker's Guide. I did not expect it to be very faithful to the book. It must have been terribly hard to adapt this text to the screen.
What I expected was, at least, just the sort of average comedy, so it was
not a big disappointment for me. There are some scenes in it that I really do not like, and the story line has also changed a lot, but, on the whole, it wasn't
bad. It is worth watching.
