A phenomenon in which sequels, follow-ups, or continuations of popular movies, TV shows, video games, or books fail to live up to the original. This often results in a decline in quality, creativity, or fan satisfaction, as creators struggle to recapture the magic of the first installment. Common symptoms include recycled plots, forced character development, and a sense of "milking" the franchise for profit rather than storytelling. Often leads to fan disappointment and internet outrage.
The sequel to this movie was such a letdown! Literally Sequel Syndrome.
