I'm admittedly addicted to this program and can watch it all day with ease. I'm disappointed with some of the reviews claiming this program is boring - I suppose this particular genre is not for everyone. At times they do not provide much detail into the processes, presumably due to the fact that the processes are proprietary, but with a basic understanding of manufacturing, much can be reasonably inferred.
The possibilities for this show are nearly endless. There are many items you will never see on this show due to the manufacturer's restrictions on depicting their process or to secure their supply chain from competitors - many very interesting items may never see the light of day on this show. I'm not the biggest fan of the handicraft items they show at times, but I can understand where others might be.
Definitely one of the Top 5 best programs ever broadcast on TV IMHO.
