These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Electric Company
The 1971 Original
Accidental Innuendo: "Billy Lick a Lolly", especially after Molly gives a lollipop to Lilly and the song says that "Molly gave to Lilly just what Billy gave to Molly."
Values Dissonance: The Punctuation Brothers sketch begins with three grown men entering a little girl's bedroom through her window. After they give the girl a lesson in using different punctuation marks, the girl's mother finds the men in the bedroom. Instead of calling the police, she expresses thanks to the brothers for helping the girl with her homework. It's implied that the Punctuation Brothers often break into children's houses.
Family-Unfriendly Aesop: Three episodes in a row (the last three of Season 1) seem to give off a shared aesop of "Never trust or befriend anyone who has been bad but seems to have changed his ways, since they'll always turn out to still be douches in the end."
Not to mention the episode about Lisa's colonial ancestor, who was believed to be a traitor. It looks like it's shaping up to deliver the reasonable aesop that if an ancestor or family member does wrong, it doesn't mean that you are a bad person. But nope, Lisa's ancestor is revealed to have been a hero all along, which leaves one with the impression that having an ancestor or family member who did something wrong is a horrible fate and shouldn't ever happen to a good person.
Rooting for the Empire: The members of the Pranksters (except for maybe Francine) are arguably much more entertaining to watch than the members of the Electric Company.
They Changed It, Now It Sucks: Fans of the original thought a revival sounded promising, as the 1970s version used both short and long segments to deliver both knowledge and entertainment at no cost to either...but then they heard about all the changes, especially the part about using full-on stories and actually requiring the viewer to pay attention throughout. (Although to be fair to the new show, the fact they want viewers to increase their attention spans is actually a pretty noble cause.)
Unfortunate Implications: Several promos for the new series, which ran before its debut, showed the 1971 lightbulb for a second before shattering into the new logo.
What an Idiot: The Pranksters. They're supposed to be evil, but their only ambition is (as stated in the pilot) to "take over the neighborhood". The town/city, fine, as at least then you've got at least one position of actual power from which you can try to bring other places under your control...but the neighborhood?!
