My problems with this movie
1. If Patrick/Jack hate each other that much, why do they live next to each other?
(I know Lu's Patrick's daughter, so he probably wanted to keep an eye on her.)
2. If Lucy (I assume her name is) is Patrick's daughter, and the mother (Emma) has been killed..
Why don't you claim/take your daughter, move far away instead of let your kid stay with some @sshole you don't even like?
3. Why would you put your daughter in a basement where there's access to the outside, or it has at least where those creatures can come in from the outside?
She would have been much saver in a closet or garage.
4. After they met the girl (who was pregnant) shoots off the creature, suddenly the rest of them creatures start to surround them.
But between the time Patrick chained him and they found the girl, there was already (at least) 48 hrs passed.
Why didn't the creatures showed up earlier, but only after the preggie killed that single creature?
5. After the girl said "I believe they're in the walls" and you put your ear to wall and hear a creature crawling down.
Why don't you shoot some bullets into the wall?
6. If you live for 9 yrs in the same empty town without any new provision of supplies, how can you still find food in any of the other houses?
Why not ransack the houses and store all the food/ammo at one place?
7. After Patrick got attacked by the creature Jack 'refuses' to shoot.
Jack doesn't 'turn', but still let's himself killed on the end of the movie.
I would have shot Jack a silver one between his eyes.
