I Am Legend alternate ending

By now, you've probably spied the alternate ending to I Am Legend floating around the Internets, but just in case, its embedded below. Like just about everyone else I've talked to that has seen this ending, I love it. It is such a better ending to the movie than the cheap Hollywood no fear grenade ending we got in theaters. If you've read the book, you know why Robert Neville is the Legend, because he killed all the vampires, so he was a legend to them (like how Richard Matheson inverted the mythos there, making Dr. Neville the legend as opposed to the vampires?). This ending still didn't completely get to that, but the shot with Will Smith looking over at the wall to see all the pictures of the vampires he tried to "save" was extremely poignant and powerful.
