Here we are: two travelers from a distant futuristic world arrive on earth... one is on a desperate mission to preserve a life, another is an inhuman killing machine determined to eliminate the woman who will give birth to the saviour of an entire race.
So what could we call this killing machine? It's almost like he's some kind of destroyer, or eradicator... sort of like an exterminator or something. What's the word I'm looking for... something that -terminates- things? Hmmmm....
Anyway, the protector (who swiftly doffs the white tunic he stole from Luke Skywalker in favour of local clothing) finds the young woman first and impregnates her with a future-born hero-to-be. The evil uhhhh... "exterminator" kills some rednecks and steals their guns and clothes, then attempts to locate the woman by visiting her workplace and asking around by looking menacingly into people's eyes and repeating her name threateningly.
Then begins a desperate race for survival as the seemingly deathless and unstoppable "exterminator" pursues the couple across the countryside. At some point he may acquire boots and a motorcycle, but I'm not sure.
Perhaps, in an exciting finale, he will attempt to crush them under the wheels of an enormous tanker truck full of... acid. Then the truck will crash. They will be saved... but no! He will then re-emerge, as strong as ever. He will kill the protector and pursue the girl into a meat packing plant, where in a terrifying finish, he is pushed into a large piece of industrial chopping machinery, and destroyed once and for all.
But maybe I'm extrapolating too much... after all, I did stop watching this movie after Mr. Protector magically impregnates Sean Young by kissing her at a bar, then tells her the child will be born in 3 days.
The costumes and effects are great in this movie... I loved them the first time I saw them on Star Trek: Next Generation too! Sean Young does another great turn as an unemotive Replicant, and career sweat-hog Stephen Baldwin is also on board as Young's Fat Cop Boyfriend. Not sure where he fits into the plot though... maybe he's an import from a different James Cameron movie?
