I know I usually don't go this far, but last night's episode of House was by far the best dramatic television I've seen in a long time. The episode would have been good without an interesting premise, but the producers chose to wallop us over the head with a nice (albeit obvious) surprise at the end.
Big ol' Spoiler ahead.
Revealing at the end that the whole episode is a House hallucination makes the episode akin to a Tennesee Williams' play. Everything needs to be reviewed because it's all coming from House's psyche and his feelings. So rather than the events being actual, they are emotions in House's mind. I nearly lost it when House apologized to the shooter, wherein he is essentially realizing in his mind that his attitude has been wrong all along. That's truly spiritual healing coming from the self.
Hopefully they wont take it quite that far next season though...
