This is a tricky thing to review. I love the story & have read it many many times & I know the details inside out & back to front.
The cast are stellar & the performances are excellent but as a fan of the original I found the adaption quite irksome in places.
In the original, the book has a voice of it's own (almost) with foot notes and asides. these are dropped entirely from the adaption with some of the text clumsily shoe-horned in to characters dialogue or as additional exposition. This for some reason grated with me, every time.
Personally, I felt that an adaption might have worked better with a 'narrator' for the book, or at least for the footnotes but perhaps they feared it would make it more like Hitchhiker's Guide.
Either way it's an excellent audiobook worthy of your time, but fans of the original may find some of the changes a little jarring. New listeners will enjoy every second of it.
