A year after running over a fisherman and dumping his body in the water, four friends reconvene when Julie (Jennifer Love Hewitt) receives a frightening letter telling her that their crime was seen. While pursuing who he thinks is responsible for the letter, Barry (Ryan Phillippe) is run over by a man with a meat hook. The bloodletting only increases from there, as the killer with the hook continues to stalk Julie, Helen (Sarah Michelle Gellar) and Ray (Freddie Prinze Jr.).

Critics Consensus

A by-the-numbers slasher that arrived a decade too late, the mostly tedious I Know What You Did Last Summer will likely only hook diehard fans of the genre.

Rosalind Bentley

Minneapolis Star Tribune

Even though the murders are gruesome, the film is not scary, nor is it clever. We've seen this many times before, but with different titles and different stars.

Rated: 1.5/5

A cheesy and sometimes melodramatic slasher film that is certainly not one of the best, but... It's directed better than a lot of the slasher films in recent years.

Rated: B-

The climactic showdown underwhelms, but Gillespie brings it back for a spectacular final shock.

As a horror experience centred on the slasher subgenre, “I Know What You Did Last Summer” is merely competent. I would recommend it to those new to horror, but those with more experience with the genre will likely find it boring. [Full review in Spanish].

I Know What You Did Last Summer may certainly be one of the more entertaining of teen slashers from its era, but it has aged about as well as milk.

Rated: 6/10

It's better if you go in completely blind. The movie has a way more interesting plot that deserves to be respected. If I could give the movie 6 starts I would.

'I Know What You Did Last Summer' manages to satisfy, even if it isn't one of the strongest slasher flicks out there. The plot gets messy and the deaths don't stick out that much, though I was still suitably entertained. It is paced quite well, the run time flew by for me. That's even with me having seen it before, way before I logged my thoughts online but I still remembered most of it. The cast, for me, are the best feature of this movie. Jennifer Love Hewitt is the standout, comfortably the best performer here in my opinion. Sarah Michelle Gellar is good too. The dudes aren't as memorable, Freddie Prinze Jr. is decent but Ryan Phillippe's character is lame. It's interesting to see D. B. Cooper, I mean Muse Watson, involved though. With a new sequel coming this year, it was about time I got this logged; as well as seeing the other sequels. This makes for a good beginning.

I Know What You Did Last Summer is above average to me. It isn’t my favorite movie, and it doesn’t come close, but it was pretty enjoyable. I found it OK, but some parts, to me, were kinda cheesy. Not a bad movie.

I often get this confused with Urban Legend (1998), they are so similar in so many ways. This hasn’t aged well but it is still mostly memorable. The cast is great. It’s comparatively devoid of gore and violence. It’s even lacking suspense, it is the cast that carries it. It’s an entertaining film but not a good film. It is categorically a product of the late nineties, teen influenced horror. I prefer Urban Legend as that has a better hook but this has the better.

I Know What You Did Last Summer has an interesting premise – after killing a man in a road accident and disposing of the body in the ocean, four friends are tormented by a maniacal killer a year later. The movie has decent production values, a solid cast of young actors, and a genuine sense of foreboding, at least during the first half. Unfortunately, things slide downhill pretty quickly over the second half of the movie thanks primarily to a convoluted plot, a series of wildly unlikely events, and more bad decisions than the average teenager is likely to make, all culminating in a totally absurd final fifteen minutes. The bottom line? It ain’t all bad, but it certainly ain’t all good.
