Both of which are retellings of Richard Matheson's I Am Legend, as are the many that came before them. I still prefer the Vincent Price version of the story, The Last Man on Earth. Though Charleton Heston was pretty good in the mutant apocalypse version called Omega Man.

It's the lone human survivor realizing he has become the villain of an emerging post-human society. The Fallout video game series and Mad Max movie series have also paid homage to this.

Aaaaand... you may hate it, but Waterworld is a special entry in this lineage, in that the anti-hero is a post-human in a human dominated world apocalypse. In that way, District 9 and State Zero are sort of in Waterworld's direct lineage -- or, rather, the joining of forces between the human anti-hero and the post-human hero.

Hate to beat the old drum, but...having read the book first (by the great Richard Matheson), I HATED this film, alternate ending, or no. It misses the whole point of the nature of Legend, and ends up as a poor action film.

This ending is closer, though. In the book, Neville is the "vampire" of legend, and the vampires are the new normal...and legends are not meant to survive but in stories and warnings.

You're kidding me. They're making an entire movie out of this? Based on Richard Matheson's "Button, Button", this was a 20 min. vignette on The New Twilight Zone which aired in 1985-86. Which is all the running time you need to tell the story. If there was any doubt that brainless dumbshits run Hollywood, they're completely erased now.

Gee, I hope you can't guess the twist ending.... (rolls eyes)

This isn't how it was supposed to end AT ALL. If you read the book, you'll know how it was supposed to end.

The movie, other than the basic premise and the main character's name, was completely made up and fabricated for this movie. It wasn't a bad movie if you have no idea how Richard Matheson originally told the story, but the Omega Man with Charlton Heston was a more accurate movie that this thing and even that was way off the mark.
