I thought the story was pretty good....but

Aside from some REAL big issues that were budget related I thought the story was actually quite good and better than most Z films.... and the first chopper scene with the endless hand signals... most being the same! funny.

That said it would never happen as the Seals are part of the military and as such cannot be deployed on American soil like that. Plus how could an entire city go 'dark' and none of the citizens upload phone vid footage of what was happening? Should have been set in a less exposed location.
