As long as it's been brought up, if we were going to make a list of the worst blunders ever by a Trek captain, Kirk not raising the ship's shields in TWOK would be in my top three. Everything that happens in the story after that, including Spock's death, unfolds because of that moment of conceit or hubris. Even when I watch TWOK today, I still keep thinking maybe this time Kirk's better judgement will kick in an he'll raise shields. Dumb. Dumb. Dumb.
