Hey! Thursday again, and another AMC column on science fiction movies. This time I talk about what science fiction and historical movies have in common, which is, not a whole lot of fidelity to their academic subjects — and why maybe that doesn’t matter a whole lot when it comes to science fiction. I’m sure this is an attitude that may annoy some science purists. But what the hell, I live to annoy. As always, the comment threads at the AMC site yearn for your wisdom, so leave your thoughts there.
