I was loving the movie until...
...exactly the 1 hour mark when he is over looking the land with his wife saying "They are almost here. Dawn will be breaking soon, and with it the loss of my powers."
OKAY, so you see with you echo vision that they are LITERALLY LIKE 50 miles away with DAWN ALMOST HERE AND YOU SIT THERE TALKING TO YOUR WIFE? You can travel that distance in a blink of an EYE almost and slaughter them all without having to worry about a damn thing!
Now, first I wanna make clear when "Problems" with the story like this come up, I always never complain. You know like the people who complain about the LOTR movies, and why didn't Gandalf just fly the eagles with the ring in the envelope and drop it into mount doom? Well, I care less about that. I never complain, but with this movie it's like...
Here is an analogy: "OH NO THE BURGLAR IS ABOUT TO KILL MY BABY SON RIGHT INFRONT OF ME!! OH NO!!! *looks over to her right and sees the telephone, and loaded gun* OH NO WHAT DO I DO!! (4 seconds later) *picks up the phone to call the police while he stabs the baby to death*. It's like.. Really? The Phone?
Same thing here. Only difference is HE IS THE GUN, and the DAWN OF THE THIRD DAY is the Phone. Yeah, lets wait till there's no choice. Good job, you deserve your fate.
