A quick scan of the credits shows about 20 writers on the project. Chances are almost all of them have literature degrees. It is almost inconceivable that at least one of them didn’t come across this particular poem in their degree programs.
That is pure speculation. These are the same twenty writers who produced a story with more holes than the proverbial Swiss cheese.
These alleged literati cannot differentiate between harpies and sirens.
Harpies luring song ability is from the Dungeons and Dragons Monster Manual.
And if you are honestly suggesting that none of the writers on staff ever heard of this poem and just accidentally quoted it without realizing it, then I don’t know what else to tell you. That’s ridiculous.
Quoting part of one line from a poem with several verses is not knowing the poem; you would not even have to know what the title of the poem was (I didn't) or even if it was a poem (as opposed to say a nursery rhyme). I can quote parts of lines from several different Shakespeare plays but I would never claim to know the plays. Hell, half the time I wouldn't know which play it was or if it was from a play or a poem.
“Oh, what a tangled web we weave...when first we practice to deceive.” Everybody and his dog thinks that is a quote from Shakespeare.
"Harpies luring song ability is from the Dungeons and Dragons Monster Manual." So what? These writers with their literature degrees bow before Dungeons and Dragons Monster Manual rather than Homer? Wouldn't surprise me.
