"Laying its claim to succeed 'Scream' as a high-grossing, blood-drenched date-night crowd-pleaser... Once again, the screenwriter is Kevin Williamson, working from a novel by Lois Duncan about four teen-agers haunted by a secret: their decision to dispose of the body hit by their BMW... Though it flies in the face of credibility and becomes downright silly by its end, 'I Know What You Did Last Summer' knows its way around the rules of the popular horror-film genre: the prefiguring ghost story around the campfire, the teen-age sex that insures murder, the spooky killer, plenty of steamy shower rooms and crab vats, pop-up bodies, references to other films and television and an ending that sets the gurney for as many sequels as the public can stomach." - Lawrence Van Gelder, New York Times
