Personally I've never been into zombies and apocalypses.
However, I gave this a try and I kind of like it. This to me shows me how each and everyone of us would react in a situation like this. The actors portray just that, scared, confused and don't know what to do. I'm pretty sure most of us wouldn't know what to do in such a situation. Overall, I give it a 6.5, and worth giving it a try.
