This, the pilot episode, establishes the look and feel of this landmark series, although the plot is a good deal more straightforward than usual. Unfortunately though much of it is so preposterous that I found it all a bit difficult to take seriously. It wasn't just a matter of the (clueless) science behind it either. The guy who ups the amps was obviously only put in the story to do that; I mean, what is he, 12 years old? And then we get several minutes of the Amazing Colossal Galaxy Being rampaging through the countryside, at the end of which he (it?) for some reason vaporizes a radio tower to punctuate his Message of Peace.
Still, the monster did look cool (especially by early TV standards).
