I actually read and had just finished the story.When I first picked it up, I was a little cynical, because how could anyone tell the FRANKENSTEIN story without bastardizing the hell out of it? I'm glad that I have had the opportunity to do so, and I highly recommend it. It is a very intelligently written story. For me, the story of UNBOUND could be best described as both a tribute to, as well as an interrogation of, the original FRANKENSTEIN story by Mary Shelley. From all appearances, a lot of effort was made to capture not only the settings, but also provide explanations for characters' mannerisms, speech patterns, relationships, and so on. Aldiss' story even went so far as to feature the very same quotes that Shelley herself used in her novel.
What I found fascinating about the novel is that it provided an indepth analysis of the source material that it's roughly based on, showing how pivotal a role it had played not only in science fiction, but also in today's society.
Admittedly, I saw the film before reading the story. I absolutely hated it. The setting made no sense. What the hell was Victor Frankenstein doing in Italy? Why was Mary Shelley there, along with Percy and Lord Byron? Everything about it was crap. Even worse, the Creature, rather than being something made from sown body parts, looked like one of those creepy troll dolls from the Nineties with its red hair.
My apologies for the long rant. This is the third movie adapted by Corman based on a novel that I enjoyed, so I'm a little pissed off at him for ruining yet another gem of a story with his crap films.
