The “Terminator 1 part” is a perfectly constructed suspense engine. It introduces the rules (machines can’t feel pain, don’t stop, can’t be reasoned with), the hero (reluctant, human, fragile), and the monster (mythic in its simplicity). Without this first half’s slow-burn dread, the second half’s explosions would feel hollow. Instead, we get one of the most terrifying antagonists ever put to film — a chrome skull with dead eyes, walking toward you in the dark. And he’ll be back.
