I am actually watching this film right now on syfy, was a little dubious at first, we have so much in the way as low budget features being created at an independent level, I feel this film does deserve some credit.
The sets, some of them at least are brilliant, would not say no to having access to some of those myself. Directing, well, I say this as a film director myself, I learn all the time, both manually and technically.
Story though, I feel this could have been developed much better, like the characters, they need development through the film as they become introduced to the audiences, personally, I feel this wasn't done to much effect.
On a technical note, my only issue was the poor lighting scenes and the grainy picture, this is a problem with many low budget films and a lack of ability to light appropriately, it doesn't happen in every dark scene thankfully and I have seen worse grain on other films when in confined, dark spaces (Wolf Creek, a good film, let down by this technical issue), my only other little issue is with some of the effects, it's 50/50, some are orchestrated brilliantly, others are more 'what the hell was that?', but it's much cheaper to create and exploding head in edit than it is on the set I guess.
So I rated it 6, it could have had some great potential, but hey, it got a sale and since I am in the same industry right now of low budget features have the utmost respect for those who made this film
