I've read the Hitchhiker's Guide several times in my life. The first times were in Dutch, when Arthur Dent was living in the Wieringermeer, the area were I grew up, as a translation to a Dutch audience of a boring area where not much ever happened.
Sasha and I saw the movie years ago.
The Restaurant at the End of the Universe, the 2nd novel, is a great read to and I know it well. But the 3rd through 5th were new to me. I was very disappointed in part three, part four was fine and only part five became somewhat interesting again.
