Huge fan of the novella, Can't stand the movie.

Rating: 1/10 (27 April 2014)

**Warning, spoilers off the port bow!**
Let's be clear, the only reason I gave this movie a 1-star rating is because there was not option to give it zero.
First off, although the film shares many plot elements from the book, it misses the entire point of the story. The Novella is titled "I Am Legend" because Neville discovers that the "monsters" he'd been killing all this time were actually sentient creatures who had set up their own society, and, from their perspective, he was the monster. He was the bogeyman that they told their children about at night. He was their legend or myth.
In the film, however, that interesting twist on the classic zombie/vampire story just gets tossed out the window in favor of a lot of "Rawrs" and a big BOOM! Because that's what audiences want, right? They can't possibly have sympathy for the creatures, or maybe have their prejudices challenged, lets just keep the creatures (who turn out to be intelligent in the novella) as mindless raging zombies.
One more thing that grinds my gears about this movie is that they even hint at the creatures being intelligent, only to completely drop it and have them get blown up. When Neville holds one of their females hostage, the creatures look at him as though they're scared, and even step back. But then, it cuts to them just rushing him, back to being the mindless zombies.
My recommendation? If you want a decent adaptation of the novella, watch "The Omega Man", but steer clear of this one.
