: Spock trying to plug vent with his hands. Someone as smart as Spock had to know this wasn't gonna happen, right? ""I'll spread my fingers out to cover more of the vent! that'll be even more effective!"
Obsession is a good episode? A living creature that can travel at high warp speed, penetrate shields and screens and then a simple 'reverse the fan' in a crewmembers quarters sucks it out of the room?
As soon as the creature left the planet----it stopped being a good episode.
