Query: Disappointing

I had high hopes for this video especially considering the cost and Caterpillar endorsement but was disappointed. My son loves watching big earth moving equipment and out of an entire 1-hour DVD there was maybe 15 minutes of good scenes. Part one was kind of bizarre. Most of the 1/2 hour was spent on Glacier National Park ,some obscure circus in Wisconsin and a toy train. And a large portion of scenes with machines were mostly old footage of antique tractors. I also did not like the video quality. Most of it consisted of 1 second clips strung together. Part 2 was better but still not what I was hoping for.
