Very authentic in that it focuses on the human interactions between only a couple of people. At the beginning, all I was thinking was, this is "Dawn of the Dead Part 2". It slows down just a bit in the middle, but after watching it all of the way through, I understand their goal was to show more of a human side to what would be going on in your head if you actually had it in you to survive that long.
This starts off focusing on soldiers or people who think like one. There is no "zombie housewives" story line here like on Walking Dead. You may shed a tear for the old woman who is dying....but you don't pause to slice her head off when she changes.
Romero would be proud. These are the slow moving zombies, but the sheer numbers of them is what does you in. They don't say it in the movie, but in the deleted scenes, they do let on that it is not a "virus" and that anyone who dies comes back, even if by natural causes.
This was blood, head shots and body parts getting chopped off in a desert with guns and real scenes that have you on edge even in the day time.
This should have been in the theaters but it lacks big names and huge CGI effects.
It does NOT lack good acting. Both main characters really pulled their weight...and they left it wide open at the end for a sequel with a different focus.
This was hard to watch at times because they do try to get you emotionally invested in the characters and what is going on.
Watch it....even if you don't like zombie movies.
