The sudden taking over of COLA by one, Roy Schestowitz and his lackeys
William Poaster and Mark Kent reminds me of a Twilight Zone episode
"To Serve Man"
Basically the storyline is about some aliens that come to earth and offer
as a token of their benelovance, cures for disease, high technology,
eternal life and so forth to the humans on earth.
In a NUTshell, they are the best thing that ever happened to earth and
they are admired and accepted by the earth people.
Unfortunately as the story concludes it turns out that the aliens have
come to earth in search of a food supply and in fact the earthlings that
are willing boarding the alien's spcecraft for the trip to the "planet of
paradise" are actually being fattened up to become food for the aliens.
The title of the Alien's "How-To" book is "To Serve Man".
