Query: Could have been worse

There is really nothing compelling about this film. While the concept is not terrible - rather deadly, somewhat mutated "zombies" overrunning the earth in the far future (2400 or something), across a barely surviving earth, the actual execution leaves much to be desired; not the least the gaping plot holes.Above all, why can't the humans just drop a whole bunch of big bombs, or a nuclear bomb, down the hole with the "machine"? Or can't they cave in the hole and seal it like the Vikings seem to have done in the year 600 or something?The acting is exaggerated, with dull uninspired characters.So what's good about it? Well, it's not just a zombie movie. And the several times over post apocalyptic world is well done for a lower budget film. On the other hand, there is really no depth or "insight" from this film, like 28 days later.
