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.
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.
