It was a terrible movie. -The locked supermarket down the block that somehow wasn't broken into was a way too convenient source of unlimited food, and what made it even more ridiculous was the random employee that worked for the supermarket just so happened to be part of the group and have the only key into the place.
-Why were there caged birds in a grocery store?
-Why did the monsters make no effort to force people to see them but yet do stupid things like rock the car?
-Are the monsters everywhere? As soon as the other pregnant woman gets a view outside the window she immediately sees one.
-Giving birth at the exact same time
-Fucking rowing a boat blindfolded for that long? Yeah no.
-One scene pretty much wipes out the whole group save for the two MCs and the kids and yet we're to believe nothing happened to them again for five years straight?
The movie kinda fudges up the book a bit. The book explains more and stuff. The book is told in three different time periods.
Also, yes, the creatures are everywhere. Globally, everywhere, the book says they're literally all around you at all times. ---
