So what did people think of it?

I thought that, for what it was, it was very good, perhaps brilliant. When compared against actual, proper zombie films, it holds it's own a little but is no masterpiece. It evoked the tone of 28 Days Later, though, and actually has one of the more convincing dystopian landscapes I've seen in a horror film. It really did unnerve me. And, the scene in the house with all the zombies scared the living daylights out of me, and I don't know why. I was truly bricking it. But the beginning was slow and the ending dragged, however I am capable of overlooking this for what the film is, which is impressive on such a budget. I'd give it a solid 6 or 7 out of ten, and if I had to watch it again, I wouldn't grumble at all.
