Blending the romantic-comedy genre with zombies could have resulted in all sorts of bad cheesiness, but the film manages to be refreshingly original and funny without laying on too much cheese.
We mostly bought things we could use to make somewhat tasty meals without power: Cold cuts, cheese, hamburger buns (there was one lonely package on the shelves when I got to it), pickles.
The dial-controlled technology and lower temperature made the oven easier to manage and allowed slices to be reheated without risk of burning bits of cheese on the cooking surface, which fouls the taste.
