This is one of the best documentaries I have ever seen. The camera-work, writing, music, editing are all at their best. I've seen it more then once and will continue to watch it whenever I want to see a great documentary. It not only teaches the viewer about Grand Central, but also about the history of trains and the history of transportation in the US. Filled with great stock footage one can really see the past. The first time I was in New York after seeing this documentary I had to visit Grand Central. I probably would not of done this had it not been for this documentary. To me, for a documentary to actually move someone to visit a place that is the ultimate 10 star review.
