I know it's basically a horror movie but..
I'm so sick of watching horror movies where the characters behave incredibly unrealistically. Of course there is a certain suspension of disbelief when you are watching any genre films. Whether that is science fiction, horror or kung fu.
But you can't just defy the law of gravity because it is inconvenient.
Characters that are in the middle of a zombie virus outbreak zone decide they should 'split up to cover more territory'.
Heck no! I'd be telling them to cover the left hand of the hall, I'll cover the right side and bubba here can cover the rear.
I do not want to give away any spoilers. It is an okay film. Better than some of the recent horror-thrillers I have seen (cough cough 'Camino').
But I must insist that horror works better when the behavior of the characters follows natural patterns of behavior, not convenient plot points.
