Could have been a lot better if plot/logic gaps addressed

Rating: 6/10 (14 December 2007)

I'll second that the film captures viewers' interest through first 2/3 of the film, and then it goes Hollywood schlocky and looks for a pat ending. Will earned his salary, and the set designers and location scouts did a great job and hopefully were paid well above scale, which must have left insufficient funds for the the CGI folk and the script writers.
So some problems I had with the story -- spoilers for sure: 1) So um, how did the later introduced pair of characters drive to and out of Manhattan? Bridges down, tunnels too (or if not, zombie-infested)...
2) Did the storyline change in the cutting room? Dr. sets animal trap and captures girl zombie, male leader zombie howls, Dr. falls for same but even more creative animal trap set presumably by male leader zombie, male leader zombie captures but doesn't kill Dr. in later dock encounter, male leader zombie tracks Dr. back to his lab.... um, why didn't the whole story line of zombies are evolving and are regaining "human" emotions get explored with this "love rescue" setup? Who is the monster, etc., etc.
3) Dr. is this Time-magazine-cover superstar virologist. How does handing over a single vial of a problematic test vaccine help without the means or associated research to synthesize more? Hundreds of more zombies on the scent, so hiding in a cubbyhole will save you? 4) Lot of deer in an unbalanced ravenous carnivore environment.
5) I lost the logic where Dr. is flatly reciting the numbers of outright dead, infected, immune -- sounded like no good scientist would believe that given large numbers of theorized immune why he would be the last human on earth. Isolated islands, small population areas, areas with no caves/permanent structures to shield sun's UV, Government pathogen barrier facilities, etc.
