The only drawback of the show would be how they make the research process look somewhat easy, and how the information you find has a simple flow from one step to the next. I've found myself on several occasions explaining to people that there are a team of professional researchers around the world conducting this research. This is their full-time job and the show has the budget to pay them.
At any rate, I've marked my calendar. I have something to look forward to on those cold winter nights in February. Yay!
