Favorite Part
is after the first kill and the husband and wife are now in bed post-coitus, she mentions something about the body being buried in the backyard and if will someone find it,
implying that the couple dragged the corpse out of that shed into the backyard and dug a 6 foot hole to bury him in,
then afterward (probably several hours) finally had sex after how many months/years since the husband's paralysis set in?
but the whole idea of the movie is that the husband's impotence was cured by the hot act of his wife murdering a lover mid-intercourse,
so the dude's sportin' a woody all the while they're disposing of the body, then get it on?
