Very entertaining, true to form, Indiana Jones . . . fast action, almost impossible feats, German/Russian military on his heels in a race to discover the hiding place of the 13 crystal skulls. I like the story and consider it the best of all, especially since I discovered it's based on a book detailing actual research. Now I want to read the book that inspired the movie! Also loved the 50's setting with all the period props and music. I definitely recommend this movie and think it's worth 2 hrs of most people's time!
