Plot twists so wild that they forever changed the perception of a particular work

I don’t know why, but I just suddenly felt like discussing this trope as something about the phenomenon that I personally found to be fascinating was how a work that starts off as ordinary suddenly becomes so much more well known due to an infamous twist that it changes the way its viewers look at it.

However, I don’t know what the trope is for when again a particular work is suddenly known for a particular twist, but it’s just something that I wanted to discuss, so I hope my post finds people well as I simply wanted to have a meaningful discussion on such a phenomenon.
