Both films.......not sure I get their defense
Ok so first movie they shield the windows and stuff. I know there is a throw away line that "this stuff isn't suppose to happen here" so that's why they aren't stronger. Yet still just like the second movie the women hide in an apartment with a reinforced door. You have all night to get into a place. The walls aren't reinforced so just take a chain saw through the walls or even a simple shotgun got him through in 10 seconds.
For the first movie why not just drive a truck full speed into the house bam instant entrance
