The custody (?) situation ....
I thought I was paying attention, but it must have waned - so, Patrick was the little girl's biological father, but he "caused" (I guess) her mother's death by drunkenly walking away from their car (which she appeared to be inside with the doors locked), so the other guy just ... took the baby? Was he a family friend or were he and the mother having an affair? Or was he married to the mom and Patrick was the one having an affair with her? And then Patrick appeared to have "put her down" after she (the mom) was bitten - but he kind of had to do it, right? WHAT THE HELL WAS HAPPENING?!
And Patrick sure seemed to be hunky dory with the fact that the other guy (who took his child or something) allowed his beloved dog, his only friend in the world, to be horribly slaughtered by a zombie WHILE THE ZOMBIE WAS IN THE SIGHT OF THE OTHER GUY'S GUN. I mean ... ??????? Totally preventable!
Maybe I really wasn't paying attention at all ... I give it a 5/10 for various WTFs, unless someone can adequately explain what I missed (if it was there in the first place).
They're coming to get you, Barbara!
