Artemis Fowl (2020)

Artemis Fowl (2020) fundamentally betrays Eoin Colfer's acclaimed young adult series by transforming a morally complex child criminal mastermind into a generic heroic protagonist. Kenneth Branagh's Disney adaptation jettisoned the book's clever heist structure and moral ambiguity, resulting in a muddled adventure that pleased no one. The film's 30% Rotten Tomatoes score stands in stark contrast to the book series' 85% audience approval, and it outperforms only #7 The Scarlet Letter in critical reception among this list. It was dumped on Disney Plus with no theatrical release, grossing zero traditional box office revenue.
