Plot twists are great. Who doesn’t love a good plot twist? We all love to get the rug pulled from under our feet while we’re watching a film, and then we rewatch the whole thing so we can see if we can catch the telltale signs of the act that has already subverted our expectations. And a good plot twist gets embedded so deeply into your psyche that the mere mention of something like Fight Club makes you remember the moment where it’s revealed that Tyler Durden and the Narrator are one and the same. If I say Oldboy, I’m sure you start thinking about the terrifying scene where Oh Dae-su learns the truth about his daughter. And even before I can finish saying the words Kahaani, I’m certain that you’re already picturing the scene where Vidya Balan pulls out the fake baby bump.
