Seriously ? Why has this become a ‘classic’. It’s ok at best. The events follow those of the hitch-hikers guide to the Galaxy and roughly develop the plot further but in truth apart from a (very vague), existential discussion there is not a lot in here. There are some modest laughs but it is extremely weak. It was only once I re-read it that I understood why the film series stopped at the first book. The film studios were not ‘stupid’ they were in fact wise..
