I don't think it was a waste of an hour. Yes, a peak time viewing TV slot is always going to demand a bit of sensationalism and big projects with big funding need to be seen to produce big results. And yes, there was an awful lot that was missed out regarding Stonehenge - but I found it interesting non-the-less and I thought that the discoveries relating to Durrington Walls, the Avenue and the Cursus were fascinating.

As you say, there is no concrete proof that Durrington Walls and Stonehenge were linked, but the circumstantial evidence looks quite compelling. Although to declare that Stonehenge has been 'solved' is a bit of a tabloid approach! I'm sure that the surface is only beginning to be scratched.
