Why Didn't Steven or Anna Choose Themselves to Sacrifice?
This was the most unrealistic plot point in the film and the one that makes me think (as others have suggested) that the whole thing was simply Martin's revenge dream.
99 out of 100 parents would choose to save their children instead of themselves. I suppose Steven & Anna could be that one set of parents who valued their own lives more than their children's, but that seems unlikely considering how much time they invested in their kids.
Food in Films: So many to choose from! Martin loves his french fries (as does Kim), Steven loves his mashed potatoes, and Bob apparently used to love his cinnamon donuts until Martin cursed the family. :(
