This is how I felt about Battlestar. I barely remember watching the original series as a kid, but I just remember a couple of character names, Cylons (which I thought were cool), the space ships, and the human in the dark room ontop of the pyramid shape the Cylons talked to. That was it. Then I watched the reboot, and was shocked by the religious overtones. Clearly, I never researched anything about it until that point, and then it all made sense.
I'm nervous about Buck Rogers (biddybiddup, what's up Buck!) might turn out the same way on a reboot.
