A depressed guy moves into a haunted house with 7 demons, each corresponding to a deadly sin. But, they're all trying to help him get back on his feet; Pride helps with self confidence, Lust helps him get laid, etc.
I would watch the crap outta this like wow
Envy: "Glut, back off the guy, okay?"
Gluttony: "I'm just saying he could stand to gain a few pounds! I made spaghetti!"
Sloth: "After we eat, it's gonna be time for a nice nap. We've earned it!"
Pride: "Damn right we did!"
