Sadly, there is not much new content in this series that has not been covered in numerous other documentaries or science or history series. A lot of teasing at the commercial breaks, with little to reveal after. I have no issue with exploring to find newer science on a previously explored site and coming up empty. That's the nature of exploration. But please don't belittle your viewers intelligence with the false hope of a new reveal "after a few words from our sponsor". The sites are interesting as is. Trying new technology on these places is interesting. Just don't try to hype it up. The approach kind of reminds me of a ghost hunting show format. Interesting sites with interesting science and history - poorly delivered. UPDATE: Season 2: Season 2 adds a new tech adviser Stefan and greatly improved scripts, locations and best of all - the childish teasers prior to a commercial break leading you to believe a major discovery would follow an ad for whatever are 95% gone. This is more what we have come to expect from The Science Channel. I have revised my rating from a "5" for Season 1 to a "7" for Season 2. Well worth your time now. The episode in Israel was especially well done.
