Somebody needed to slap the mother for doctor shopping during a zombie apocalypse.
The son is not too popular on the IMDB message boards. There's several "hope he dies" threads. One of the funnier comments was something like, " I hope if he gets better that he walks in front of another deer, or maybe a gorilla".
The farm was a cool setup. The house didn't look very secure, but with a secure house, that's the kind of place I'd look to lay low during the ZA.
