This show, as you might have already learned from the summary and title, is all about huge and amazing engineering marvels. The first time I watched it, I thought it was only information, but I realized that they actually record how it's built, and what's going on! They're not just saying "They do this and that to do that and this", but they go a step furthur which probably attracts much of the audience: They make it seem like a story. It has suspenceful moments, like they are putting in a piece that might fall, or even disaterous such as a storm knocking over a crane (This didn't happen, they are just examples).
Information and a story put together make one awesome show.
