Much like Bram Stoker's "Dracula", Mary Shelley's "Frankenstein" is a story we all think we know, but really don't. Very few films have consciously attempted to follow the novel too closely (which shouldn't detract from the excellent James Whale/Boris Karloff film, or its masterpiece-sequel, "The Bride of Frankenstein). Thus, everything popular culture "knows" about "Frankenstein" does not originate from literature, but from films. This is a shame, in a way, because the novel itself is, if not the progenitor, an early vessel of so many archetypes found science fiction and horror.
The basic plot remained intact when transferred to other media. Swiss medical student Victor Frankenstein discovers the secret of life (which he never reveals, lest someone repeat the mistake). He then puts together a body, essentially a man, from various corpses. He then becomes horrified by the creature he has built, and abandons. The creature, suffering a great deal of neglect and abuse, still manages to get a thorough education, and learns of his lineage. After murdering Victor's younger brother, and framing the family maid, the creature tells his (admittedly) sad tale to his "father", and then demands a mate. Victor, in a panic, agrees, then thinks better of it at the last moment, destroying the new bride. In retaliation, the creature murders all of Victor's loved ones (including his wife), and leads Victor on a merry chase across the world.
Most probably know that Mary Shelley wrote this book in response to a challenge issued by Lord Byron, during a vacation at Lake Geneva. (Along with this story came John Polidori's "The Vampyre", the first English vampire novel.) Most probably also know that Shelley went on to write other works of imaginative gothic fiction. Still, her modern reputation rests with this book, understandably.
As stated, numerous archetypes (themes, plot lines, characters) are present here. The basic fear of what evil technology may bring along with the good is a central theme, as is the warning against playing God. So is the implicit admonition to be responsible in all things, be it during innovation or being a parent. The creature is, for all intents and purposes, an android-everyone from Gort to C-3PO owe their existence to the Frankenstein monster. And the monster that slays all but one protagonist is a staple of horror, be it traditional monster movies, like "Alien", or more realistic slasher movies like "Halloween".
But, as I noted at the beginning of this review, certain of these elements have been lost in most interpretations. The creature is actually intelligent, and well-spoken, quite different from the inarticulate grunts or slow, half-sentences of the movies (again, no disrespect to Karloff). Further, while the films have made lightening a staple of the creatures creation, Shelley never really explains the process (probably knowing that she might interfere with the plausibility of her work). Finally, one of the staples of the films is the explanation for the creatures "evil" nature. Often, the problem lies with the brain used, which almost invariably is a criminal brain, or is damaged before implantation. In the book, the creature is really a child that's horribly neglected, but with the strength and intelligence to strike back: id without superego, and without restraints.
Thus, "Frankenstein" will be a new experience for readers who have never experienced it. Unlike "Dracula", there aren't any moments where a reader might look up and suddenly realize how quiet it is in the house, or how dark it's gotten outside. In that regard, "Frankenstein" has not aged particularly well. Throughout, however, it is a moving, disturbing, depressing, but also a touching and beautiful tale. Those qualities have withstood the test of time. While it is not always a rollicking adventure, it is a rewarding read.
