1. What "test" was Beth mentally preparing for? 2. Why were the zombies obsessed with attics? 3. Why was Beth plastering the attic walls with mud? 4. Why didn't that motel parking lot zombie eat Zach? He was RIGHT THERE! 5. Why wasn't Beth covered on mud? She crawled out the ground. She'd be filthy. 6. Zach and Beth had sex and nothing happened? Shouldn't he have been peeing maggots or something?
1. I think it was just a tactic her parents and later her boyfriend realized could for some reason keep her distracted and in the house, thinking she had a big test "tomorrow". She seemed incapable of understanding that they were lying and doing so repeatedly
2. No clue.
3. Seemed like all of the zombies were trying to make their personal spaces more like graves/the ground.
4. How come nobody noticed the ridiculously acting zombie mailman, or the ridiculously acting zombie cook, or the other zombies that everyone somehow manages to not realize are no longer dead. Beth's parents were the only ones that went "Hey, how come that dead person we know is suddenly alive, and acting really *beep* weird?" I can answer none of those questions, nor yours.
5. I assume her parents had her shower. She still thought she was a person and was doing just about everything they suggested early on.
6. One of the dozens of other things in the film that made no sense. Why was sex pretty much the only desire she had once she came back from the dead?
1. It was Either a latent memory or a way to keep her distracted from the fact she is dead.
2. Since they are dead Zombies are constantly cold as they have no blood flow. Attics are typically the hottest spot in the house.
3. To make it more homey like her grave. The dead feel more comfortable in the dirt.
4. These Zombies first instinct doesn't seem to be to eat humans though they eventually resort to it. These Zombies obviously aren't completely mindless and seem to only eat people when they can no longer control their primal urges.
5. We never saw her directly out of the ground. It's safe to say her parents showered her off prior to Zach seeing her.
6.Why would something happen? She has no functioning reproductive system and I have no Idea why you would think having sex with dead person would lead to pissing maggots or anything for that matter.
