These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Lord Barkis Bittern. Despite his snobbery, he at least seems to care about his bride, but in reality, he's a male gold digger. In a flashback image, we see a shadowy figure attacking, robbing, and killing Emily. Later on in the film, it's revealed that Barkis was her fiancÚ and murderer, and responsible for her depression. After marrying Victoria, he plans to rob her blind and murder her as well. Unfortunately, her parents are broke, and marrying Victoria to him for wealth he doesn't actually have. When he learns this, he tries to kill both Victor and Victoria out of frustration.
Nightmare Fuel: The scene where Victor puts the ring on what he thought of as a twig... and the subsequent coming-to-life of Emily.
The Woobie: Emily could qualify, in a... weird way. She was killed by the man she fell in love with, then she's rejected by her new (unwilling) husband, and THEN she ends up letting him go although he was ready to join her in the afterlife. Damn, she really needs a hug.
To be honest, all three of the leads have their Woobie moments. Almost all of which are caused by Barkis, one way or another. Victor in particular is definitely a Woobie — the animators on the film started in an interview that they endeavored to make Victor as pathetic as possible.
