Query: Remarkably short and not terribly informative.

This video is only 10 minutes long and NOT worth $15. I was very disappointed. The video goes on for about 3-4 minutes before it even shows Stonehenge. Very light on the facts or speculations about Stonehenge and the narrator's silence is filled with cheap music. If you are looking for a quality documentary about Stonehenge, look elsewhere. Such a disappointment.
