Ethics horror movies comprise a sparsely-populated genre, but 2009’s “Drag Me To Hell” is a sterling example. It is at once scary, campy and clever, but its ethics lessons are valid and even inspiring.
The story involves a young bank loan officers who allows ambition to override her natural ethical instincts, resulting in the young woman being on the receiving end of a gypsy curse. On the way to the film’s surprising conclusion, she has several ethical dilemmas to solve, with mixed results. She also eventually takes full responsibility for her disastrous unethical act, for all the good it does her. (Lesson: Don’t expect a reward for doing the right thing.)
The movie has ethical implications on several levels. It was the final film role (outside of a few cameos) for Allison Lohman, who decided to retire when she got married and decided to have children, in order to give them (she now has three) a healthy, normal upbringing unlike what the children of more career-obsessed actresses experience. Hers was off to a boffo start, too, but she chose family over fame and fortune. The film’s writer and director was Sam Raimi, best known for creating “Xena, Warrior Princess” and directing the first film in the endless “Spiderman” franchise. As a horror director, he shares the same integrity and restraint problems as Tim Burton (and Stephen Spielberg): he is often incapable of suppressing his juvenile slapstick and gross-out sense of humor, causing all of his horror movies, and especially this one, to undermine the scares with camp just as you are ready to run screaming into the street. But that’s his style: Raimi’s first bit of fame came from directing the hilarious “Evil Dead II,” best known for sui generis actor Bruce Campbell fighting a knock-down, drag out battle with his own severed hand after it has been possessed by a demon. (He finally wins by trapping the thing under a bucket, which he weighs down with a copy of “A Farewell to Arms.”)
Nonetheless, “Drag Me To Hell” is a wild ride and a fun one, though I wouldn’t recommend for children.
Ethics Alarms 
I find the initial ethics dilemma with the bank loan to be especially interesting. First, as you’ve stated here many times, people with debts have a moral obligation to repay them. The old lady wasn’t quite in the same boat as a dumb college student who took an easy, PC degree only to find it’s not marketable, but the principle is the same. Instead of begging for an extension, she ought to have considered the alternatives which the protagonist laid out. At the suggestion that she look to family for help, she said, “I don’t want to impose”. My response was, “So you’d rather impose on a complete stranger who doesn’t owe you anything?”
Now, if I was in the protagonist’s shoes, I would’ve granted her the extension, with the warning that next time I may be ordered to foreclose. If the boss had a problem with that, I’d tell him, “Look, she been sticking with her payments up until now, she’s not some deadbeat that we have to keep pressuring to pay, so I think she’s earned some slack. Also, at her age, it won’t be much longer before it’ll be her heirs’ problem, and they will most likely either let us have the property or be better able to pay it off. Either way, all we have to do is wait.”
It’s a classic non ethical considerations vs. ethics problem. She’s been told that the super-ambitious suck-up creep is closing in on her desired promotion. Her boss is obviously a jerk. She knows what’s right, but she can rationalize that she can do more good for more people if she gets the promotion.
In addition, the behavior of the old woman is definitely unethical. Causing a scene in the bank, openly begging for special considerations, courting emotion and trying to make the young woman look and feel guilty is unforgivable—that would convince me that I couldn’t trust the old bat.
