[Chronic Diarrhea]

I liked that ending OK, but it doesn't make much sense with some earlier scenes in the movie.

*Spoiler Alerts!!!!*







Remember when Will Smith is marking down a new journal entry, and he talks about how the zombies have lost ALL semblance of human behavior? That would mean that main zombie would have never stopped at getting to Smith, and wouldn't have recognized his (prior) wife/girlfriend. Unless he was somehow the last remaining member of his species that still had some human characteristics left.

I guess it's pointless to debate any plot holes in a sci-fi film, because you aren't supposed to ask questions. Regardless, a vaccine still wouldn't completely restore the infected back to their original human form. As in 28 Weeks Later, even those who carry a resistance to the virus still aren't completely human.
