While I'm a huge fan of the new Sci-Fi series Battlestar Galactica, I'll admit that its oft-criticised use of conventional "Earth stuff" like suits and neck ties, Hummers, various weapons, and other things bothered even me a bit. I rationalized it by deciding that, since this was a TV show with a budget, they just didn't have the time or the money to make everything look futuristic and different. In my mind, whenever I saw one of these clashing items, I simply thought to myself, "insert expensive effect here." The show was plenty good enough to watch for other reasons.
Then I read this blog entry by show creator/producer Ron Moore, in response to a viewer complaining about precisely this thing:
The props are all deliberate choices that imply more than just a passing connection between our world and the world of Galactica and there are deeper connections yet to come.
So it would appear to not be a case of budgeting, but of some long-thought-out plot twist yet to be revealed. Now, this is the guy who ended the second season of his highly successful, and already renewed, series by having the humans surrender to the cylons. He's capable of anything.
Which is most of what I enjoy about the series. You never can tell quite where it's going, but (to me at least) it's always fun getting there.
