I've only seen about 20% of the Outer Limits series. Some episodes are great, others just mediocre. However, "Think like a Dinosaur" stands in a league of its own. Never have I thought so much about an episode of a sci-fi series. The greatest aspect of this episode is its ability to elicit intense introspection; to imagine yourself in the protagonist's shoes and know you must make such a difficult decision. The clear, warming humanity of the "unbalanced equation" is overwhelming, which is why the choice is so painful. The ending still gives me chills. Imagine what the protagonist must be feeling when he sees her again. This episode is a brilliant depiction of morality and ethics clashing with science. I haven't yet seen the topic handled better.
