It goes without saying that a plot twist can either make or break a movie. A great twist will recontexualise the movie's events in a clever or unexpected way, while a bad twist will generally feel like it was deployed for mere cheap shock value.
2020 may have been a lighter year for cinema than anyone could've ever expected, but it still served up a slew of tantalising plot twists (which we won't spoil here).
But these 10 films went in another direction entirely, delivering twists that, rather than elevate the drama or enrich the characters, were just flat-out stupid.
These revelations, whether genuine, earnest attempts to be clever or more wilfully trashy rug-pulls, represent 2020 cinema at its most mind-bogglingly dumb, fielding out sappy, silly, and flat-out ridiculous revelations that weren't at all justified by the material.
Whether you were left laughing, sighing, or cringing, these 10 films were largely talked about because of their big reveals, which were at least divisive if not universally reviled in some cases.
Then again, some of these films would've evaporated from the cultural conversation within seconds were it not for these attention-grabbing, thoroughly idiotic reveals...
10. Melanie Is Secretly Crazy - Fantasy Island
It's totally apt that one of 2020's stupidest movies also plays host to one of its most inane plot twists.
This horror-themed reimagining of the hit 1977 TV series Fantasy Island follows a group of strangers who visit the titular island, with the promise that their grandest fantasies will come true.
It doesn't take long for the wish fulfilment to turn weird and then deadly, leading to the howlingly ridiculous reveal that all of the events on the island have actually been the vengeful fantasy of just one person - protagonist Melanie (Lucy Hale).
As it turns out, all of the other guests were in some way involved in the accidental death of Nick (Evan Evagora), the object of her affection who she was supposed to go on a date with the night he died in an apartment fire.
Effectively, an insane Melanie wanted to get violent revenge on those who deprived her of Nick, though in an hilarious bout of comeuppance, one of the surviving guests then uses her own fantasy to "reunite" Melanie with her lost love.
At this point, a zombified Nick bursts out of the nearby water fountain and drags her into its depths. It may be a thoroughly dumb series of events, but at least it probably made you laugh.
