Frankenstein 451

A movie set in a dystopic future* where a brilliant but insane surgeon, Victor "Fools ! I'll crush you all ! " Frankenstein, horrified by having to deal in his hospital's emergency room with the consequences of a disastrous conflagration in which many firefighters are severely and tragically injured or killed , decides to help spare the lives of future emergency service workers by creating replacement firemen from the usable body parts of corpses.

Although initially highly successful, resulting in public acclaim for the good Doctor and numerous humanitarian awards, it inevitably All Goes Horribly Wrong when, due to a simple error in the "accelerated learning" used to condition the reanimated bodies for their work, the whole lot of them (except the very first one, one if the heroes of the movie, who dies in a tragic, noble and self sacrificing way right at the end, like the Terminator in Terminator II) become obsessed with burning down bookshops and libraries.

In a classic slash-and-spatter action hero finale, involving lots of fire, explosions, crashing vehicles, collapsing buildings etc. the "Frankenfiremen" are destroyed in some suitably spectacular and appropriately ironic way, like them being crushed flat by having shipping containers full of Kindles dropped on them from a great height.

* Actually, is there any other sort ?
