When I watched this as a kid, this was state of the art, but geez was this primitive. In real life was our military technology really this backward? Despite all, I enjoyed it.

It's another good episode. But if it requires light to keep going, then a can of spray paint applied to its "eyes" should stop it.

That globe at the start of the movie looks like the thingy Jackson Grimes took a pic of in England, when he fled the US after losing the 2008 election. I wonder if they shot this picture in England??The fat, balding guy who looks like a Jew, was on the 0uter Limits in the 1960's and Mama's Family in the 1990's he never seems to change. I think he was also one of the Germans on Hogan Heroes sometimes but, I'm not sure as I can't ger into stuff with army guys.

This was a surprisingly effective entry, in spite of there being not much of a story here. It mostly concerns the guys trying to avoid and/or thwart the attempts of a superstrong robut to destroy them. Why does it want to do this? What happened to it up in space? Did some sort of hostile intelligence reprogram it? These questions are never answered, though there's some speculation. The familiar attitudes are trotted out here -- we are taught once again to beware overenthusiastic creator scientists, and to value caution and suspicion of that which is not human; and I have to wonder if this didn't seem a little hackneyed even when this originally aired. But still the tension and danger is ratcheted up quite nicely, and there's even a larger than usual body count in this episode. I'm always impressed how such a limited environment--a submarine--can be used to create suspense so effectively. It's interesting to contrast this with the previous episode, about an intelligent and cunning "alien" individual out to harm the Seaview and by implication the human race: here the danger is much the same, though the menace is mechanical and silent and single-minded. But it's just as effective and I enjoyed it almost as much.

very good worth your time
