[very common Trope] A universally supposed Good thing turns out to be a Bad thing

[u/macho_boy-420]

1. The Hero defeating the Villain (Gameoverse): You'd think that after the defeat of the very evil Big Bad means the day is saved, right? Well, no. Because the day is about to end, along with your entire world, your friends and family, all because the hero did what they thought was the right thing.

2. Believing into Getting adopted to a new loving "Family" (The Promised Neverland): Hey, Sweetie. What's that? You think you're going to live with a new caring and family? WRONG. You're actually the next new meal to bunch of demons. Hope you're doing well in the next life.

3. The 'Great Beyond' (Sausage Party): same premise as the Promised Neverland. The food all think they going to a wonderful place called 'The Great Beyond', being treated as Nirvana and sees us as their Gods. Well... You all know what we do with food, right?

I mean to be fair the vast majority of the movie is Ewan McGregor and Scarlet Johanson on the run trying to survive after learning the truth and escaping the cloning facility, so it's not like an end of the movie kinda twist.

Yeah but the first act is pretty long

People always say "The trailer spoiled the whole movie!" and the trailer is almost exclusively Act 1 and early Act 2.
