Visually impressive, but I had one big problem with this movie.
Characters do too many foolish things for me to be compelled by what is happening.
Leaving the antibiotics in the woods after all the doctor risked to get them, using the key to get to the food (which obviously shows the resistance has help inside the house), eating the grapes, leaving I don't remember what object on the table for the villain to see...
Too many character actions were unrealistically foolish and clearly written in to propell the plot. It made it unbelievable and took me out of the movie.
The world was great, the characters ruined it for me.
