Yet this is still a wonderful book to read. Sure, we know there aren't any real Martians. Put that aside. The straight forward Victorian narrative style is odd and strangely formal by today's standards. But that's part of what sets the scene.
Here is a book that has all the basic elements of the genre - and Wells got them right the very first time. Better, in fact than most modern writers. There aren't any heroic moves we can make to save ourselves. There's no hero that defeats the Martians through cleverness and clean living. The Martians are centuries ahead of us technologically and we're going to lose. Period. Is that realistic enough for you?
How about a writer that predicts tactical battlefield lasers, chemical weapons, armored mechanical fighting vehicles, interplanetary spaceflight and computer controlled robots up to ninety years ahead of reality. Pretty impressive stuff that STILL hasn't come to pass in some cases, even though we can understand such things now. Imagine someone who takes a horse-drawn carriage to town conceptualizing battlefield lasers. That's what Wells did when he wrote this novel.
But most of all this book is there for its commentary on humanity - Victorian imperialism and lack of humility, the arrogance of invulnerability just waiting to be burst. Watch a cultured society crumble in the face of harsh reality. Watch us devolve into elemental things once more, as we learn what it means to be dominated as we have dominated other, less advanced cultures. Wells' book was meant as a commentary on English Imperialism and arrogance, but that lesson still has relevance today, whether you apply it to superpower politics or global environmentalism.
Take the time for this book. It's worth it.
