no logic at all ....
i liked the concept of the movie, but the logic of everyone except for the dad is ridiculous ...
the rest of the family are complete idiots, from letting the stranger in the house on the ONE day of the year you can kill people, and after he goes missing the kids just run off all over the house??? ... i don't even care about the ending with the neighbors it was fine, the whole point of the movie is killing was legal.
and why would they not have a safe room to lock them selves in for the 12 hours??
the movie is so bad, the son ruined the movie.
