While I watched the special, and had exactly the same questions the scepics had, I don't think the evidence could be totally discounted. The research was incomplete.
As for the information about the ossuaries not coming out in 1980, I am not surprised. Antiquities Departments are full of politics, and considering how long it took for The Dead Sea Scrolls translations to be released (decades and decades), I'm not surprised that these ossuaries have not been studied until now. The politics of religion, scholasticism, and politics complicate this issue, and of course, involve three of the world's major religions, someone's going to have a hissy fit.
The Israeli's limit study of historical and ancient artifacts because they consider these the history of their ancestors and they have a way of handling those items. The orthodoxy in Jerusalem is consulted as to how the tombs and the artifacts and any remains are treated, and that hampers scholarly research as well.
I couldn't care less if Jesus lived or not, though I found it exciting to think that this could be the tomb of the Jesus family. To have proof of a first century rabbi who set out to change Judaism and whose teachings were used to found a new religion that has had so much influence on history was interesting to me.
As a Buddhist, many Christian concepts are foreign to me such as the resurrection or Jesus's mother being a virgin (what has that got to do with anything?), but archeology is one of my interests, and making a connection to people who lived long ago and in a very different culture is fascinating.
I feel like the special was like-one third of what it should have been.
