Plus the original script had everyone acting out of character, a failure of the author to be familiar with the basic “rules” of the universe (Star Fleet simply doesn’t have skeevy 1950’s style drug-pushers in their ranks), preachy, completely ham-fisted anti-Vietnam stuff and a totally horrible climax.
Y’know how, in the filmed ep, Spock has to stop Kirk from saving Edith and how powerful it was that Edith was the one woman Kirk was willing to consider sacrificing the Enterprise for? In the Ellison version, Kirk just…freezes in indecision. Whee. Big drama there. And totally in character for Kirk. :rolleyes:
Also, there was some torture porn thing about the drug dealer being sent to the heart of a star and being forced to die over and over again.
