Enjoyed this better than I thought I would and rather liked the revelation at the ending, but the creatures didn't suddenly transform and they certainly weren't zombies....
...as we find out, they were mutants who evolved into different creatures over many generations and that took over 800 years. Not sure how it would make the film better by showing that via convoluted flashbacks, the explanation was enough for me.
Yea I know they ain't zombies I was lacking of words and Zombieland was on my mind.
I expected less too and quite glad on the film.
Just that it kinda turned out to be more of a horror than a sci-fi movie (and I'm a big sci-fi fan) with all those typical scary looking mutants.
