Putting this novel merely into a science-fiction frame wouldn't be fair.
Therefore "The Invisibile Man" has more to share with the tradition of the Victorian literature with a pleasant shade of British humour not that far from "The Picwick Papers".
Yet, this book is extremely modern in its own way.
The revolutionary approach of H.G. Wells to the topic of an extraordinary-power such as invisibility can't be denied.
Whereas other novelists would have insisted (and later did) on the possibilities given by the new discovery to a single human being, Wells pictures the invisible Griffin as a deconstructing man. A selfish, egoist, arrogant scientist who was looking for a way to superiority and descended into an abyss of terror and worries, just like a fugitive.
For Griffin invisibility becomes quite early a cage and also a kind of alibi for justifying his very frequent Mr Hydesque moments. One may think he became like this because of his new condition, but I suppose he wasn't that far from this personality even before as a pennyless albino student. He wanted revenge for being emarginated from the rest of society, but at the same time he wouldn't have been able to stand other people.
The funny side of the novel is placing this irascible, unhappy "superhero" in the middle of the quiet Sussex countryside, surrounding him with dull and nosy peasants. From this enlightened choice comes a long chain of impiteous situations that makes the reader happy, but the poor Griffin scorned.
