Very interesting. It essentially tells three seemingly unconnected stories with the only connection being the house. I have a feeling there's more to this than meets the eye however. I wouldn't describe this as a "Dark Comedy" though. It's really a mystery, and an anthology. The animation was superb, although facial expression was lacking due to the techniques used.
Interestingly, this movie stars Jim from Friday Night Dinner, and Bellatrix
Lestrange from Harry Potter.
