Horrible. It simply doesn't "scream" scary to me at all. Not sure what point the directors were trying to get across since I didn't feel any sense of horror during this whole 2-hour movie. Honestly, I felt like it was a waste of my time. One particular scene opened the threshold to my negative review. This was the scene where the crew crept inside of a zombie-infested building and made their way through the room by avoiding the hibernating zombies. Unfortunately, it really made no sense at all and here's why; When they first entered the building, the nervous crew member screamed but none, I repeat, none of the zombies were affected by it. Yet, when the woman knifed the zombie in the head to avoid detection by the other hibernating zombies, the knifed zombie slid to the ground and hit many metal trays towards the ground which awoke all of the hibernating zombies. Yeah, it shouldn't make sense since the whole movie is based off of an unrealistic "zombie" apocalypse, but this particular scene just did it for me. The directors should have made that scene a tad more realistic if they really wanted to portray this movie as a real-life situation that could happen to scare their viewers. All in all, don't waste your time watching this boring, inaccurate zombie movie. I'd rather watch the walking dead series than this garbage. That's my genuine opinion on this movie.
