Alas, Poor Scrappy: Bart generally comes off as an unlikable putz for most of his screentime, but it's hard not to feel sorry for him when we see his utter horror at realizing he's been bitten and hear his pitiful begging for C.J. not to leave him behind while zombies close in on him.
Broken Base: Among zombie-movie fans, whether this or the original Dawn is "better".
Crowning Music of Awesome: The use of Johnny Cash's "The Man Comes Around" over the title credits and Jim Carroll's "People Who Died" over the end credits.
Damsel Scrappy: Nicole, whose stupidity forces them to prematurely flee from the safety of the mall (though Steve shares equal blame). Unlike Steve however, she survives right to the end.
Also worth noting that Steve is meant to be a Love to HateJerk with a Heart of Jerk. Him being a stupid, selfish asshole fits. On the other hand, Nicole is meant to be one of the likeable characters, so her poor decision making is a lot more infuriating.
The security guards hold the protagonists in contempt for destroying a fictional store called Metropolis upon entering the mall. Around a decade later, Zack Snyder had these exact same complaints leveled at him – twice.
The third act of the film ups the action by having the characters leave the mall to avoid going mad from isolation. Fast forward to another Zack Snyder film where the characters are already mad - and imagine themselves as gun-toting action heroines. One of the sequences involves zombies too.
Seeing Lindy Booth as a sweet Distressed Damsel becomes rather amusing as she'd eventually get typecast into playing murderers. Likewise she ends up trapped in a gun shop, which makes it hard not to think of Cry_Wolf where she plants a gun to frame someone for murder and then fools everyone with her Nice Girl façade.
Looking at this version, a lot of the CG shots are pretty apparent (especially in the scene where society collapses around Ana as she's escaping from her neighborhood). Takes away a bit from the scare factor.
In the DVD commentary, director Snyder cheerfully points out a specific example- when they cobbled together the overhead shot of Ana's neighborhood via CGI, they failed to give some of the houses any street access.
