"Specimen: Unknown" (S1 E22 of the original Outer Limits) was the highest-rated episode of the original series, and I admit it has some good parts. But it's also one of the DUMBEST episodes in a series that excelled at ominous dopiness. The scientists of Project Adonis, a research station in orbit 1,000 miles above the Earth, find some fungoid-looking things - "space barnacles", they call them - adhering to the station's hull and bring them in for further examination. They speculate that they are some kind of alien spores that have been just "floating around in space for millions of years." This is ALIEN LIFE we're talking about, and they treat them as casually as if they were Earth mushrooms. They don't keep them in sealed containers; they don't use isolation and containment glove boxes to handle the specimens; they casually handle them with their bare hands, and keep them in what look like modified coffee cans; they don't pack them securely when it's time to return to Earth. Even after one of the scientists is killed by one of the plants - which of course is unwitnessed by the rest of the crew - they don't do anything to change their handling of the mushroom-shaped organisms. All these safety measures things had been thought of, designed and invented when the show was filmed. But of course, if the plants hadn't "gotten loose," there would be no (dumb) story, would there?
