From the bewildering shark saga “Jaws: The Revenge,” which Ebert labeled “stupid and incompetent,” to the cringe-inducing comedy “Sour Grapes,” where humor crumbles under its own weight, Ebert’s disdain is palpable. He didn’t just dislike these films—he dismantled them with a ferocity that left audiences reeling. The 1989 disaster “Rude Awakening” was branded an “insult” for its lack of insightful satire, while “Caligula,” with its graphic excess, was dismissed as “shameful trash.”
