These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Music of Awesome: Even among those who didn't like the film, almost everybody has agreed that the soundtrack is very good (particularly the scenes that used a Mahler piece and in Teddy's first dream).
Moral Event Horizon: Dr. Naehring arguing in favor of leaving the patients shackled to the floor to potentially drown. Quite probably an intentional Kick the Dog moment to solidify his image as a mad Nazi doctor in Teddy's Andrew's imagination.
In the one scene in which he has any dialogue, Ted Levine delivers a gripping Character Filibuster on how violence is a gift from God (which arguably doubles as some variant of "The Reason You Suck" Speech to Teddy/Andrew about what the warden sees as the inevitability of his lobotomization)..
Paranoia Fuel: The imagined Rachel says that in fifty years the Ghost project will be operational. The book takes place in 1954. It was published in 2003. Subverted. There is no Ghost project.
