Freddie, as a guy who has worked on many, many of this type of documentaries, let me tell you there is very little for you to worry about.
It kinda goes like this....A network exec does some market research into what might be interesting to a target audience. Then hires a productions company to produce a show. The production company hires a 25 year old kid just out of college who will work for little money to research, shoot and round up some "experts". The kid "writes" the show and the network exec makes sure everything is hyped up. Many facts get turned into twisted interpretations to draw an audience. Then they go hire a music composer (me) to make everything sound mysterious, crazy and cool.
After all that they run out and sell advertisements...
Do the people who produced the show think the world might end? Not a chance.
