Interesting idea, but it seemed to drag for me. The whole thing was rather inert until the scaly alien showed up toward the end shouting like a drunken street person. Interesting design for the space vehicles, though; they look like space-suit helmets! Can't believe they spent the money on two of them. And at least Jonathan Harris got to stretch a little with his old man bit in this one, and Mark Goddard seemed to be genuinely getting a kick out it. Hey, maybe I'm projecting, but in some of these ya gotta take your enjoyment where you can get it. And Judy's new togs still seem cool some 43 years later.
