7. Sweeney Todd

Yes, some fans already knew the deal, as goth musical fans tend to arrive pre-spoiled. But the story is designed to reveal the meat-pie horror gradually, with creeping realization and dread. Sadly, the trailer leaned so hard into “winking” at what the secret was, it went blind. Oh, the irony.

8. 10 Cloverfield Lane

This movie thrives on one delicious question: Is the alien threat outside real, or is this man just being super paranoid? This uncertainty drives the narrative forward. Then, BAM!, the studio releases the full trailer and, as it often happens, shows way too much, and preppy much confirms that the truth is out there and it’s not friendly. It’s hard to have a mind-blowing twist when you’re being spoon-fed the smallest details.

9. The Sixth Sense

Remember this one? Of course you do. Everyone knows the “I see dead people” line. The twist is legendary, to say the least, the kind that became pop culture shorthand for “Holy smokes! I need to rewatch this immediately!” But before people could enjoy that succulent turn of events, the soundtrack tracklist rolled up with a title along the lines of “Malcolm is Dead.” Thankfully, not many people read track names back then. In fact, most tracks back then looked like this: “Unknown Artist—Track01.wav” Still, if you paid attention, you’d be spoiled.
