Well I very much enjoyed a scene in Elfen Lied. Most of them I thought the ultra-violence was kinda neat, and fairly disgusting, but the scene after (hopefully this works) those kids beat Lucy/Kaede's dog to death in front of her, where she rips their bodies to shreds. The logical part of my brain thought death was too harsh a punishment for killing a dog, especially since their kids. The more emotional part of my brain was rooting for it all along, and wished it had lasted a little longer, so they could tell what was about to happen before they were shredded. They beat the only thing a little girl ever loved to death in front of her. They murdered a innocent little puppy. Fuck them. Kill them in the most gory, painful, awful way you possibly can, and hang their dismembered corpses from nearby trees as a warning.
