Mr. Plinkett is the fictional, deadpan reviewer created by Mike Stoklasa for RedLetterMedia, best known for the feature-length Star Wars prequel reviews released around 2009 and 2010. Short reaction snippets of his mumbling delivery circulate widely on YouTube, in video essays, and on meme soundboards, where editors lift his sighs, asides, and flat interjections. The exact one-second 'oh' has no documented single source moment and is best treated as a floating reaction sample. It endures because the character's weary, unimpressed tone is instantly recognizable to film fans and works as shorthand for disappointment.
