I just remembered this ramification of my terrible opinion that "love as a trope sucks":
Do you know when all hell's breaking loose and one of the characters does something really dumb because s/he sees someone familiar in the midst of the hostile crowd?
Just picture the scene: everyone's running from the zombies and, just as they're entering the helicopter/boat/escape device, someone in the crew sees a former love interest in the midst of the walking dead crowd, gets paralyzed and then bitten?
Yeah. Go figure, that got old for me too.
