Douglas Adams was incredibly brilliant.

This set of books never fails to make me laugh out loud at the wonderfully hilarious and weird way Adams looked at the world and the universe. It has so many quotable instances and is an absolute pleasure to read - I would recommend it to everyone.

There is a movie, but it only somewhat follows the plot line of the first book. I enjoyed the movie for entirely different reasons than I enjoyed the books, but I don't feel the two are really comparable.
