In fact Sulu is a hero in it, because he refuses to beam down extra phaser power packs without a direct order from Kirk, or Starfleet.
He (correctly) doesn't trust Captain Tracy.
BTW, a great actor, Morgan Woodward. He's about to turn 90!
Didn’t know he’s still alive but then Shatner is mid 80s and many stars and guests are deceased :(
I admit it ... I can’t get enough of the remastered episodes either for their video quality or the revamped SFX.
PS - obligatory Trek nitpick: in most episodes a phaser on ‘kill’ will simply disintegrate the target and it disappears.
In this episode we hear Spock refer to ‘the remains of several hundred Yang bodies’ as if phasers were used to kill but the corpses remained. Odd.
