Basically all trailers in the last ten years. They reveal so much you are just watching a cliff notes version of the movie.

The worst is when you go see a comedy and the only funny parts were in the trailer.

Terminator 2. The ad campaign and trailers revealed what had the potential to be an amazing reversal of expectations well ahead of time. I actually got to see it with a friend who was out of touch enough to not have seen any spoilers; I wish I'd had his experience.

As ridiculous as this movie was, I always thought that the trailer for Star Wars Episode I : The Phantom Menace shouldn't have shown Darth Maul's double bladed lightsaber.

I basically don't watch trailers anymore. I'll read a synopsis and look at some aggregate scores.

Ideally though I'll just ask someone I know for what they've seen that's good.

The only time I watch trailers anymore is when I trust the people involved to leave me with nothing but confusion and questions. Like the Death Stranding trailers that Kojima puts together.

I saw Get Out without knowing anything about it. Very effective movie if you were expecting a romantic comedy like Meet the Parents, lol. If I'd seen a trailer I wouldn't have been nearly as blindsided by the horror turn of events.

Also, that couple second teaser before the trailer starts. Why do they do that shit now?

Lincoln (2012). They totally gave away how it ends.

Prometheus showed literally every good shot from the movie including the titular spacecraft colliding with an alien spaceship at the very end, but then maybe that’s ok because the trailer was much better than the actual movie.

For me it was Marvel Studios' Civil War.

Leaking Spiderman's appearance was too much. I don't watch movie trailers at all anymore.

Basically all mainstream ones since the 2000s. Nowadays I skip trailers entirely to not spoil the movies for me.

The trailer for Green Lantern gave away the best parts of the show, but it wasn't actually good. I saw the trailer in the theater, turned to my girlfriend and said, "I think we may have seen everything good about that movie." Turned out I was right.

Terminator: Genisys has the big reveal right in the trailer. I think if they had left that out it could have at least redeemed that steaming pile of shit a little bit.

I mute trailers and just watch the first 20 seconds to see if the film's atmosphere matches my current mood. Haven't had a trailer spoil the film in years this way

The trailer for The Martian (2015) contained every plot point, including the finale.

The short episode summaries on Netflix that show before you watch an episode often spoiler the main plot or even the plot twist. I will never understand why they do that.

The last Johnny english movie. It was just an extended Trailer.

Suicide Squad. 😢

I saw a version of the trailer for Split (2016) that revealed the plot twist. I was glad I already saw the movie, but my parents did not watch it because of that.

Everyone of them

I never watch Trailers fully. Just 30seconds to get a feel of the movie.

I saw a trailer for this which I'm pretty sure contained at least 75% of the movie. I never bothered to confirm that.

Astonishingly, the trailer for Triangle Of Sadness reveals a lot, even the whole timeline of the plot, while the movie achieve to surprise and astonish with how much more there is to it.

I was afraid I wouldn't enjoy it because I somehow "knew" how it was going to end, but oh, my, that was only the surface and the craziness ran m7ch, much deeper.
