Admittedly, a lot of people aren't that educated in the field of science. Most people probably couldn't even define it nor the scientific method.
Frankly, science is rarely seen as a topic of entertainment, but rather as a another day at school, when you'd rather be lying back and watching a show that requires less brain cells. Hardcore science, like any hardcore discipline, is very esoteric and requires great expertise in order to understand, and to the layman, it will simply fly over his/her head. And yet, it is so essential to everyday life. Nevertheless, people like Carl Sagan have learned to bridge that gap and popularize it to the common person who may not have their PhD's in quantum physics yet.
Daily planet is a good medium to bridge that gap as well. It's an amalgamation of interesting breakthroughs, new technologies, and often scientific outlooks of everyday life. It presents science news that even the scientist viewer was probably not aware of yet, and it would be a welcome alternative to reading scientific journals.
Yes, the show does its homework in making sure that information is accurate. But, because the information needs to be simplified so the average viewer can understand, some of the information presented will be incomplete, stripped down, and skewed if you happen to interpret it incorrectly. So, watch the show to gain a perspective of the science that affect your everyday life, but take it with a grain of salt. Watching the show won't get you your PhD after all.
