Robinson Crusoe is best taken at two levels, the literal adventure story of survival on an isolated island and as a metaphor for finding one's way through life. I recommend that everyone read the book who is willing to look at both of those levels. If you only want the adventure story, you may not be totally satisfied. The language, circumstances, and attitudes may put you off so that you would prefer to be reading a Western or Space-based adventure story with a more modern perspective.
Few books require anyone to rethink the availability and nature of the fundamentals of life: Water, food, shelter, clothing, and entertainment. Then having become solitary in our own minds as a reader, Defoe adds the extraordinary complication of providing a companion who is totally different from Crusoe. This provides the important opportunity to see Crusoe's civilized limitations compared to Friday's more natural ones. The comparisons will make for thought-provoking reading for those who are able to overcome the stalled thinking that the educated, civilized route is always the best.
One of the things that I specially liked about the book is the Crusoe is an ordinary person in many ways, making lots of mistakes, and having lots of setbacks. Put a modern Superhero (from either the comic books, adventure or spy novels, or the movies) into this situation, and it would all be solved in a few minutes with devices from the heel of one's shoe. Maybe I'm old fashioned, but I liked the trial-and-error explorations. They seemed just like everyday life, and made the book's many lessons come home to me in a more fundamental way.
Have a good solitary trip through this book!
