Accidental Aesop: Don't text/answer your phone while driving. The reason why Anna winds up in the morgue is because she paused to check her phone while driving and another car hit her.
Best Known for the Fanservice: Several critics noted that many viewers will probably watch the film just to see Christina Ricci in a sexy red dress and later nothing at all (though it's arguably more a case of Fan Disservice, given the circumstances Anna finds herself in and the film's grim tone).
Complete Monster: El(l)iot Deacon is a funeral director who appears friendly and sympathetic on the outside, but is actually a psychopath with a tendency to bury people alive. He manipulates them by posing as a psychopomp who can communicate with the dead as he prepares them for burial using techniques that won't kill them, so that they stay alive until buried. He keeps a photo collection in his bedroom of everyone he's buried, and it's strongly hinted that he's buried as many living people as corpses. The film centers on his preparation of Anna Taylor, during which we see just how twisted Deacon is. Later on, he deals with two people who have found him out in very different ways: recruiting one in whom he sees a kindred spirit as a Secret-Keeper, and goading another, Anna's boyfriend Paul Coleman, into a car accident while he's drinking heavily and then taunting him about his failure before finishing him off directly on the slab.
