I think the storyline of the movie was decent, but there were so many mistakes it's impossible to list them all. To name a few: they were not smart with the windows. You can see cameramen in the cabin windows toward the end of the scene in the cabin. There are also LOTS of missed opportunities - one being that the good guy leaves a rifle with the bad guy after fighting with him. The guns seem to have endless ammo, they run instead of utilizing vehicles, and they seem to all be able to find each other in the woods remarkably well - too well.
I'm giving it a 5 out of 10, because it's decent enough. Just don't watch it if you're one to really pick movies apart. You won't enjoy it.
