A too familiar theme - zombies - treated in decent manner. This is the virtue of a film who not impress but , helped by a reasonable story, using in smart manner some cliches, offers thrill and fair developement of crisis situation and pretty definition of characters.
Two thieves attacked by two guys immune to gunbullets. A young man saving them and introducing them in terrible reality defining the town. And the ways to escape against a zombie pandemic.
Nothing new, obvious not memorable but clever rhytm of story offering to viewer source of interest. The end - not so surprising, just works in expected manner.
