9 Reasons Why Scream 3 Is Not QUITE As Bad As You Remember It
4. The Voice Changer
While there are countless shining examples of a terrible or simple plot device being used in such a way that it makes audiences think the mind behind them was some creative luminary - see the briefcase in Pulp Fiction as a shining example - it is much easier to find examples of the opposite; a clever plot device that the production became so enamoured with they would use to a ridiculous and overbearing degree. As a prime example, see the Batmobile in the Arkham Knight video game.
The voice changer in Scream 3 is a case of overuse of a great plot device to make up for substantial holes in the plot and give the mortal killer seemingly supernatural abilities. At its core, the device would mean that the killer could use the "Ghostface" voice while wearing the costume. It would also allow the killer to record snippets of another person talking and then play these back, kind of like a more sophisticated version of Kevin McAllister's video tape trick from Home Alone. If the filmmakers had used it correctly, it would have been a fantastic addition to any villain's arsenal, even allowing a killer to give himself an alibi.
Making one person's voice sound like another was impossible and it still is nearly 20 years later.
