I've decided to not attack all the prior reviews, those are their opinions, therefore, here's mine.
From the synopsis, I could tell it'd be yet another independent zombie flick in the veins of 28 Days/Weeks Later (albeit in a confined space), so I knew not to expect perfection. Still, for what I watched, it really wasn't that bad.
Story was simple, a terrorist with an extremist patriot complex believes he sees political hypocrisy in his own nation and wishes to see something like a "reset" (as I'd call it) by exposing deadly secrets in a government building. Those secrets being a deadly virus that changes the mindset of a person, making them highly paranoid and overtly aggressive. Yes, it's basically a total rip-off of 28D/WL, but it didn't stop me from enjoying. In fact, before all the action really starts, you get to see all the little things in normal lives, including that of a divorced couple (along with a small touch of humor before total insanity breaks loose), play out.
There weren't that many jump moments, but what there was was pretty decent since it went very well with the story. Some pretty crazy death scenes, a few twists here and there, and one particular crazed zombie that seems like a dimwit rip-off of a zombie from Land of the Dead (remember the one that figured out how to use a machine gun? Watch this and you'll see which one's the rip-off).
Acting, like that of any low-budget indie, isn't perfect by any standard, but it's still better than some I've seen (2012: Doomsday always comes to mind as the worst indie film I've ever seen in ever single aspect), so there's a plus. Some people, sadly, do die off (in which I mean I wish they hadn't, but that wouldn't be good for the death quota in making a film like this, would it?), but nonetheless, the main character, who's been in search of one particular person in a quarantined building, does have reason, in the end, to hope. And the reason for that hope may end up giving bad nostalgia for those in Oklahoma City, 'nuff said.
All in all, especially for an obviously low-budgeted indie zombie film, I pretty well enjoyed this. Nowhere near perfect, but I could at least handle it for what it was worth.
