Alternate Character Interpretation: Some are left with the impression that Gordon was not really Ax-Crazy, but instead suffering from a case of Demonic Possession. This theory is supported by some deleted scenes, which show that the Simon "personality" is actually a murderous demonic entity which hops from victim to victim, preying upon their weakness as a way in ("I live in the weak and the wounded"), and then using their bodies to commit murders. However, it works just as well as a metaphor as it does literally. The movie leaves it ambiguous.
Awesome Music: The score, by Climax Golden Twins. ...Okay, so maybe the term "music" isn't really the proper descriptor, but for an atmospherically-inclined work of avant-garde soundscaping there's a surprising amount of normal musical structure surrounding it. It's also chock-full of little ear-worms... The soundtrack album isn't so much a bogstandard selection of tracks used in the movie as it is its own, self-contained experience; a companion piece to the film.
Harsher in Hindsight: Basically any moments with the Danvers State Hospital becomes this considering the building would later on be torn down afterwards to make apartments, despite frustration with many locals and such that the place was to not be torn down.
The final call to his wife in his mind. The phone Gordon is using is broken, and his mind is attempting to piece together a scenario where his wife and daughter were still alive, and apologizing for his actions. The scene where he realizes what he'd done in particular is quite sad, seeing as he himself looks broken in that moment.
