3. CGI Zombies
It's inevitable that in a project like this, it's going to need a lot of visual effects, and I have no problem with Marc Forster employing CGI to easier convey the massive zombie hordes rushing to make meals out of the humans. It is an effective tool for depicting scale, but this becomes troublesome when the director also uses CGI for some of the more close-up zombie images, such that when we see them diving over walls and leaping forward, there's absolutely no weightiness to the physics, and our mind knows this, subsequently rejecting it. As a result, a lot of the zombie attacks appear extremely artificial, as though the humans are running from a computer simulation - precisely because they are. Though one can appreciate the need to convey the speed and ferocity of the zombies, could this not have been achieved with wires and some trick photography? It surely cannot have been as garish an option as this risible CGI dreck.
