SPOILER dont read this if you havent seen the movie please
Here is what I came away from it after just watching again for the umpteenth time. I tend to let my imagination run away with loose ends and come up with suppositions based on minor details I string together.
1) As has been pointed about before the gas station was abandoned. Obviously it was in fact up and running with no one at the helm. Anyone who has ever worked near gas pumps knows that you don’t leave them active when your away I am placing bets based on the condition of the gas sign and the type they don’t have credit card pumps. So odds are it is pay at the counter in the sticks as usual so someone should have been there if it was active.
2) Next Ted probably is the one who infected Eve I the script was either edited at some point or altered and never carried through. After all that is the guy who’s cabin it supposed to be and he never shows up but the cabin is unlocked for the weekend. That would be my next guess if grabbed her through the bathroom window because it takes them what seems like forever to get to her after that initial thump. Plenty of time if he doesn’t damage her too badly to heal back up considering how fast those head wounds healed on Dash’s face.
3) Ok another thing and I don’t remember which of the demonic/undead/possessed say this but they reference that it isn’t just there this happening but everywhere. I am pretty sure it was the Dash one when he tied to a chair. They seem to be telepathic to a degree since they have info they shouldn’t have about the others so it might be possible they are aware of the other monstrosity’s doings. That one is very thin I know I am really stretching it on the telepathic thing since only seems to happen like twice. Once in the woods with the Matt thing knows about Amber and baker getting it on. Also the Dash thing in the woodshed.
Over all there are some other things I think this could have been an A league movie if they had flushed the plot out a bit more and maybe with 10 or so more minutes of plot supposition. If they had made it more a global thing and left it hanging with the survivors heading out to find out what is happening in the world. Rather than what the hell really happened like they did. This is all just one persons opinion by the way oh one last thing it is nice they don’t try to explain exactly what the ‘things’ are it takes up back to Alien and so for when they didn’t try to explain ever damn detail and left it up to our own imaginations to supply ideas. Though in this case they do need to tie up those loose ends that I already pointed out while leaving what people are turning into as a mystery.
