The Prestige/YMMV

"Tesla: Go home. Forget this thing. I can recognize an obsession, no good will come of it.
 * Darkness-Induced Audience Apathy: Hence.
 * Fridge Logic / Fridge Brilliance: Relates to Moral Event Horizon below.
 * Precisely. This calls back to a thought experiment done by Derek Parfit:
 * While it is highly probably that you are correct it is important to note that
 * It Was His Sled: The ending started being discussed openly almost as soon as the film came out.
 * Before that, even. In the book, the "twist" isn't a secret, you're in on it pretty much from the start. It's the tale of how it gets used which makes it compelling.
 * Magnificent Bastard: Both Angier and Borden.
 * Moral Event Horizon: The Reveal.
 * Though, on the other hand, its a little unclear if thats what happened,
 * Nightmare Fuel: The extents that both Angier and Borden went to to pull off.
 * The final shot of the seemingly endless pile of hats and the rows of shows just how far Angier went for vengeance.
 * Role Association: This is the closest we'll ever get to Wolverine vs. Batman on the big screen. Also throw in some Alfred. Not to mention Gollum is working for the Goblin King. Oh, and Batman falls in love with the Black Widow.
 * Seinfeldian Conversation: Some of the lengthy philosophizing among fans (including on this very page) as to which comes off as this. They're  Bam, done, stop writing essays!
 * Tear Jerker: On a second viewing is heartbreaking.
 * The Woobie: Tesla. Just consider this exchange:

Angier: Why, haven't good come of your obsessions?

Tesla: Well at first. But I followed them too long. I'm their slave... and one day they'll choose to destroy me."
