I was wrong about this film, watched it last weekend and thought it was great, scary as well when we first meet the vampires in the dark, chilling like. They changed the plot, but they didn't fuck it up completely. The bit at the end would have been better without the flag-waving, and didn't quite match with the title in the way it did with the book (that line is something I really liked about the way the book ended).
I liked Smiths Robert Neville, and thought the way they showed his loneliness was quite effective... a good film really, I felt abit embarresed for bad-mouthing it to people before I'd seen it to be honest, now I have to go cap in hand and mutter "yeah, was pretty good film for its class".
The book was brilliant but the film wasn't shit, put it that way.
