The bulk of this episode's reviews are referring to a "happy" ending, an ending which the spirits of the Crain family are living for the eternity and the family's living members get to continue their lives happily. It is clear that these people totally ignored or forgot the fact that the house tricked Hugh to COMMIT SUICIDE in order not to cease its actions. Let's also not forget the Dudleys, who not only stopped Hugh from burning the house down but also will end up dying in there so they stay in touch with their daughter, thus feeding it. In the end we conclude that the house manages to avoid being burned and simultaneously to guarantee its "food" by "tricking" Hugh (and the Crain's in general) and the Dudleys. So yes it turns out that "the house always wins".
