not bad

The acting, the plot - all very decent.
OK - there were some unnecessary bits which made the film go longer than it should have - so I skipped a few side-dialogues. I'd say they could cut 15 minutes from this film and it would be that much better.
Otherwise, this was a pretty decent film.

And now, time for a spoiler - a scene which took the film quality down a few notches.






Spoiler:

But yeah - the ending battle - 4 rednecks taking out the remainder of the crew - that was a bit much.

I mean, yes, it's possible for 4 rednecks to take them out, but not in the way things played out.
Given that the woman shot and hit a redneck first, and they were standing still for a second, the captain alone should have been able to take out 2 more without any problems, since he was right there with them. Yet, apparently he's developed the stormtrooper aiming disorder.
At the same time, rednecks were all sniper wannabes - I don't think they missed once - and this is against hardened soldiers (2 soldiers, anyways).
In other words, they could have made the final battle play out in a way that would lead the majority of their crew to be taken out, but the way the director/writer set it up, it was unrealistic at best.
