Good plot, pacing, and acting. Starts off right away. Usually, these types of zombie/virus flick break down halfway through the storyline leaving me screaming WTH??? Not this one. No super idiotic plot twist nor does anyone do anything super duper dumb. Story unfolds in a small town and it's escape or die. Graphically violent but you diehard horror fans may feel there's not enough. Very little CGI.
Overall a well balance horror flick. Highly recommended.
