Went ahead and watched this last night. RayB pretty much nails it. I find the argument that ET isn't a terrible game to be laughable and the "five weeks, bro, five weeks!" argument doesn't impress me much. Whatever helps Howard sleep in his crummy apartment at night, I suppose.
Was also quite amused that we get 80 minutes of build up and then maybe 5 minutes of footage of what they actually pulled out. Considering as that dig was one of the main points of the documentary, where was the "two weeks later, here's what we found" followup?
