Mick LaSalle considered the movie inferior to its predecessor. Richard Harrington, on the other hand, cited
I Know What You Did Last Summer as superior to
Scream; he described the newer picture as "... a smart and sharply-drawn genre-film with a moral center, and with a solid cast of young actors to hold it."
Derek Elley of
Variety was also enthusiastic, calling the film a "polished genre piece with superior fright elements that should perform at better-than-average theatrical levels."
Roger Ebert gave the movie one of four stars and wrote that "The best shot in this film is the first one. Not a good sign."
Entertainment Weekly praised Jennifer Love Hewitt's performance, noting that she "knows how to scream with soul". Lawrence Van Gelder of
The New York Times wrote of the picture: "This isn't real life. It's the
grand guignol of
I Know What You Did Last Summer, laying its claim to succeed
Scream as a high-grossing and blood-drenched date-night crowd-pleaser. And why shouldn't it?" James Kendrick of the
Q Network wrote that "Williamson's characters are all generic types; but they're still believable as people, and they react realistically according to the situations." Kendrick added that the film was "head and shoulders above earlier 'dead teenager' movies".
TV Guides
Maitland McDonagh awarded the movie two out of five stars, noting: "Screenwriter Kevin Williamson takes a step backward and writes the kind of movie
Scream mocks. You can see him now, soaking up videos of
Friday the 13th and
Halloween—not to mention the lesser likes of ''
He Knows You're Alone, Terror Train and My Bloody Valentine''—and saying, 'I can do that!' And boy, does he ever." Critic
James Berardinelli credited both
I Know What You Did Last Summer and
Scream with igniting a new boom of slasher films, adding: "There is one minor aspect of the plot that elevates
I Know What You Did Last Summer above the level of a typical '80s slasher flick -- it has an interesting subtext. I'm referring to the way the lives and friendships of these four individuals crumble in the wake of their accident. Guilt, confusion and doubt build in them until they can no longer stand to be with each other or look at themselves in the mirror. Sadly, this potentially-fascinating element of the movie is dismissed quickly to facilitate a higher body count. And, as I said before, a few extra deaths can only make a slasher movie better, right?" Movie historian
Leonard Maltin gave the film 2 out of a possible 4 stars; he described it as "...Too routine to succeed overall...Despite being based on a young-adult novel, this is absolutely not for kids. Still, it's a classic compared to the sequel." Motion picture scholar Adam Rockoff notes in his book
Going to Pieces: The Rise and Fall of the Slasher Film, 1978–1986 that, at the time of its release, many critics branded
I Know What You Did Last Summer as an imitation of
Scream. However, he contends that it is a "much different film", despite both screenplays being penned by the same writer:
Lois Duncan, the author of the original novel, heavily criticized the film adaptation; she stated in a 2002 interview she was "appalled" her story was turned into a slasher film.
