Fair for Its Day: While the depiction of minorities is hardly perfect, Native Americans are treated with far more respect than usual works of the time period allowed for, and Asian characters were generally treated as respectable, law-abiding citizens... when Yellow Peril wasn't in play.
The Scrappy: Finding a modern listener who enjoys Poco is difficult. A squeaky-voiced character who always speaks in rhyme and claims that speaking normally causes him pain, there are several points where he can't tell the heroes important things because he can't think of rhymes. Couple this with his naivete and you've got quite an irritating mix.
YMMV for the television show:
Alternative Character Interpretation: In one episode a gangster and his moll discover that Clark Kent is Superman. Superman's solution? He leaves them stranded on a snowy mountain until he can figure out what to do with them... and then they fall to their deaths while arguing. Did Superman do that on purpose, hoping they would kill each other while fighting, thus preserving his secret?
"Funny Aneurysm" Moment: Superman actor George Reeves died less then two months after the series' last episode aired. At the time, almost all his career options involved playing Superman, a role he had come to tire of (he reportedly never liked the job to begin with, seeing as it was the 1950s and neither TV nor comic book superheroes were seen as the potential money makers and career franchise builders they are now). Thus, the exchange between Jimmy and Superman in the show was chillingly prophetic:
Jimmy: Golly, Mr. Kent, you'll never know what it's like to be like Superman.
Two villains get caught by Superman. One tries to shoot him, to no effect. Superman demands to know, "What have you done with Jim Olsen?" You'd Expect: The two cooperate, hoping that this scary invulnerable guy recommends this as grounds for leniency during sentencing. Instead: One tells the other to "give [Jim] the current".
Two crooks who have captured Perry and Lois (and who have previously said that they are going to kill all four members of the Planet staff) ask Perry how he'd describe the route if he were telling Jimmy how to get to that house. You'd Expect: Perry realizes that the only reason they'd ask this is to record his voice for a trick phone call to Jimmy. Instead: He describes the route. Jimmy is almost killed when his acid-eaten brakes give out.
