I've posted this to my Facebook account when I found out about his passing. I feel it's best to share it here too:
I come online and find out this news, and I'm sad. For those who are unfamiliar with this man, from the 1970s and 1980s, he created many of the classic shows that still have a fanbase today. To me, I know him as the creator of the original "Battlestar Galactica" and my childhood favorite, "Knight Rider." It is saddens me to hear about this. R.I.P. Mr. Larson. Thank you for giving me "Knight Rider" and "Battlestar Galactica", which both still hold true to me now as they did then.
I will admit, I have seen a lot of other of his shows while I was growing up, including Magnum, P.I. and The Fall Guy. And I will admit, after hearing about the original concept he came up with that eventually became Battlestar Galactica, a story called Adam's Ark, which involved a spaceship of humans leaving Earth after a catastrophe in hopes of finding a new home (similar to what was on the show, except heading from Earth instead trying to find it), it kinda made me wonder why it wasn't attempted (though it's probably because of the bleakness of the concept). But I will continue to remember his work. In fact, I've started rewatching episodes of Knight Rider on Netflix. R.I.P. Mr. Larson. Thank you again for the stories you've left behind for us to continue to enjoy. And I do still believe in one line you've written: One man can make a difference. And you certainly made one while you were here.
