* DarknessInducedAudienceApathy: Every character save for those played by Brad Dourif and Danny Trejo are as violently unlikable as possible, and we barely see them (Danny's is killed very early on). Without a single character to like, and with Michael having most of his CreepyAwesome stolen by the beginning in which we see how terrible his life is, why should we watch this movie?
* HilariousInHindsight: People poked fun at how the orderlies at Michael's asylum fed him steroids due to how tall he got. This gets even funnier when in the sequel, Daeg Faerch (the actor who played Michael as a child) was unable to reprise his role because of a massive growth spurt he had between films.
* MoralEventHorizon: Michael crosses it when he brutally kills Ismael Cruz, the only guard who ever showed him any kindness.
* {{Narm}}: Michael bursting through a car windshield is followed by Dr. Loomis shouting "MICHAEL! JESUS CHRIST!" as if he were reacting to someone spilling coffee on the floor. The line even became [[MemeticMutation a meme]] in the Dread Central podcast and forums, usually used whenever Malcolm [=McDowell=] is mentioned.
** Judith's death, due to how comically oversized the WhiteMaskOfDoom is on young Michael.
* OneSceneWonder: Ken Foree.
