Intriguing sci-fi premise squandered a bit by some seriously bad over-acting (Dennis Christopher, I am looking at you) and some absurd logical flaws. Just because it is sci-fi doesn't mean that you get to throw all logic out the window whenever you feel like it, at least that's my honest opinion. Good entertainment nonetheless.
This is one of those miniseries that I wish had been turned into a full series. I loved the concept, but it seemed a bit rushed. Some of the casting was not so great. If they remade it they could probably get better actors today.
