Not bad for a director's first film

I jumped into this movie about 10 minutes late and I was just hating the cast immediately. This movie really wasn't all that bad though. The transition from things going great to things going to *beep* I think was pulled off pretty well.

A few things bugged me though:
Who are these mutants and what have they've been eating to stay alive? That dead dog looked untouched on the porch.
Why do they only come out at night? Vampire rules?
How are they intelligent enough to know which wires to cut in the engine of the van yet not know what a gun is or how to use one? (Considering the gun they found on the bus and the one on the Russian)
Also, the van battery died from the interior lights being on, why were they still looking for wires? This could just be a plausible mistake assuming the characters just brain farted about the dead battery, but all of them? Still unlikely. The Australian even mentions to his girlfriend that the batteries in the cars at the lot they found were all dead.

If this had a better cast and a somewhat known protagonist, I think it could've been a hit. The suddle directing made this movie for me. Like watching the Russian and the guys younger brother (don't know the names, not looking it up) go out to the woods all from viewing from inside the van and u see and hear is flash of gun fire followed by panic. The way the "monsters" were kept in the shadows, probably diliberatly to hide the fact they're just awful in every filming aspect. The Australian taking the map and the gun was a pretty well done too. A movie with bad acting can only be so good.

I gave it a 6/10. Would have gave it a 7 but the ending deserved for a star to be stripped from it.
