Scariest moment: The monster's scariest moment is, tragically, the result of its good intentions gone terribly wrong. Doctor Frankenstein's creation comes across a little girl picking flowers alongside a lake. Seeing how much fun she's having tossing petals into the water, the monster naively similarly picks her up and throws her into the lake. Unfortunately, the girl can't swim.
Weakness: His own insecurities, as seen when the Bride rejects him in Bride of Frankenstein.

The basic concept behind Mary Shelley's novel Frankenstein, famous adapted by director James Whale for his 1931 genre classic of the same name, is the ghastliest of ideas: a monster created from various parts of long-buried corpses. As brilliantly played by the great Boris Karloff, Frankenstein's monster is so unforgettably chilling that it's easy to overlook the fact that a figure made up of different body parts should look more disjointed and piecemeal.

Still, Karloff's incarnation of the walking dead man achieves a distinct level of horror through the monster's slightly human but mostly lifeless look. Injecting just the right amount of pathos into the character, Karloff disarms the viewer, leaving one prone to sympathizing with the beast (he just wants to be loved, after all) before doing something horrific (i.e., killing a little girl) or simply reverting back to his malevolent ways.
