Summary

While finding out the orca is often the best part of a whodunit , there are some successful movies where the adversary ’s identity is never reveal . From murder mysteries to slashers , many sub - genres center on the moment that their killer is finally unmasked . TheScreammovies even fuse Agatha Christie - dash mystery storytelling with gorier repugnance elements to leave viewers guessing who the killer was while at the same time creep in terror . However , a subpar killer reveal can sink a movie just as quickly as a great twist can elevate a genre outing .

For good example , although there are a fewgreat movies where the hero is the slayer , this twist is so well - known that few innovative releases attempt to pull it off . This is true for many classical enigma twists , from the once - shocking “ Every defendant is guilty ” to the ever - popular “ It was the hero ’s love interestingness . ” Now that many of the genre ’s potential surprises have become rote , it is increasingly difficult for writers and directors to get along up with Modern spin on old twists . As a resultant , several movies never reveal their grampus ’s individuality at all , with mixed results .
