Can you imagine if TOS was made today, how much blood and gore would've been included in those death scenes? I always thought TOS was much darker and more violent than people today give it credit for.
Amen. And it's probably worth noting that several TOS writers were no strangers to dark themes:
Robert Bloch (Psycho
), Richard Matheson (I am Legend, Hell House,
etc.), Theodore Sturgeon (Some of Your Blood,
"It"), Harlan Ellison (A Boy and His Dog,
"I Have No Mouth and I Must Scream," etc.), Norman Spinrad (Bug Jack Barron, The Iron Dream,
etc.), Jerome Bixby ("It's a Good
Life"). Heck, even Roddenberry dabbled in horror with Spectre.
No surprise that TOS did not shy away from horror elements.
