OK: so what makes a film a "10"? For me, every scene has to work. Would I take out any scenes? If so, then the flick isn't a 10. Also, does each scene move the story forward? If this is seamlessly done, then all the better. "Hidalgo" not only does this; but it does so easily, and unobtrusivesly, with the sense that the lead actor (Vigo Mortensen) is the vehicle for an ongoing, and interesting, story ... and what a story it is! Just as with the film Apollo 13, the fact that the story is based on real history and fact makes the story-telling more than a good tale. It tells us something worth remembering.
Did I mention that this is a rippingly good story? Did I mention that all of the actors are compellingly good ... including the horse (Hidalgo)? Did I mention that this movie transcends facile categorization (Western, Adventure, Drama, etc.?) This is just a damned good, under-appreciated movie.
The bonus material on the DVD is worthy of inclusion in a course on Western Civilization (a course that I've taught several times)? See this for yourself. I doubt that you'll be disappointed. In fact, I think that you'll recognize this as equal to such under-appreciated films such as "King of Hearts" and "Kasper Hauser" ... films that you'll be proud to own and to show to your friends.
