This show is a lot of fun. First off, it has the sultry Michelle Rodriguez as host, looking her sweaty finest and stalking around like a tigress in heat. Second, there are some excellent experts involved. Third, the speculation is just right; not too far "out there" but not dismissive of possiblities either. I came away thinking about the topic from a new angle myself; i.e., biological alien attack rather than robots and lasers. In the end, however, I am one of the "loonies" cited by Seth Shostak who thinks the aliens have already been here for a long long time. If they wanted to destroy us, they could have done it long ago. So I don't really fear them, even if their motives are questionable. I may, of course, be wrong. There's definitely no reason for complacency on our part. Another things this program doesn't consider is that the military very likely has much more sophisticated weapons than the ones the public knows about. So there might be more resistance from us than aliens would suspect. FWIW.
