The Story of I Know What You Did Last Summer
I Know What You Did Last Summer opens on a Fourth of July celebration gone wrong. A group of friends—including bride-to-be Danica (Madelyn Cline) and her fiancé Teddy (Tyriq Withers)—decide to drive toward fireworks after a few drinks. What should've been a carefree night ends in tragedy when their car hits someone on a dark road. Rather than call for help, they make a choice that haunts them: they cover it up. One year later, when a hook-wielding killer begins stalking them with surgical precision, the friends realize their secret has come due. The film, directed by Jennifer Kaytin Robinson, is the fourth installment in the franchise and the first sequel since 1998's I Still Know What You Did Last Summer, making it a 27-year gap between entries. It's a lot of runway for a slasher to build momentum—and the film's 111-minute runtime gives it plenty of space to try.
Behind the Making of I Know What You Did Last Summer
Jennifer Kaytin Robinson, known for her work on The Politician and Dash & Lily, took the director's chair for this reboot, co-writing the screenplay with Sam Leah McKendrick and Robinson. What's striking is the decision to bring back Jennifer Love Hewitt and Freddie Prinze Jr. as Julie James and Ray Bronson—the original survivors from 1997's I Know What You Did Last Summer and its sequel. Their return signals an attempt to straddle two audiences: longtime franchise fans and a new generation discovering the property for the first time. The cast also includes Chase Sui Wonders, Sarah Pidgeon, and Jonah Hauer-King as the younger generation of friends caught in the killer's sights. The film earned an R rating, which feels appropriate for a slasher, though that didn't stop it from pulling in $32.2 million at the box office—a respectable if not spectacular haul for a horror sequel in 2025. Metascore currently sits at 42/100, while IMDb users have given it 5.2 out of 10 across nearly 40,000 votes, suggesting a film that hasn't found consensus even among its intended audience. Movie OTT tracks where these kinds of mixed-reception films land across streaming platforms, and this one's journey to digital availability is worth monitoring if you're a franchise completist.
What Makes I Know What You Did Last Summer a Divisive Watch
Here's the tension at the heart of this film: it wants to be both a legacy sequel and a fresh start, and that split identity shows. The performances from the new cast—particularly Cline's grounded turn as Danica and Withers' work as the conflicted Teddy—suggest there's real talent here trying to anchor emotional stakes. But reviewers consistently note that the film mistakes glossy production values and recognition of the original property for actual suspense. One critic called it "a glossy, shallow reboot that mistakes recognition for resonance," and that observation sticks because it's hard to argue against. The hook-wielding killer is a visual callback to the original's fisherman-turned-murderer, but the film doesn't seem to understand that nostalgia alone can't carry a slasher—you need either genuine scares, character depth, or an interesting twist on the formula. The thing nobody mentions is that legacy sequels have a nearly impossible job: they have to justify their own existence to audiences who remember the original, while also standing on their own for newcomers. I Know What You Did Last Summer doesn't quite manage either. That said, there are flashes of potential—the Fourth of July setting creates a summer-dread atmosphere that works better than you'd expect, and the film's central mystery (who did the friends actually hit?) generates some narrative momentum even if the payoff feels inevitable. It's the kind of film where you can see what the filmmakers were reaching for, even if the execution falls short of the mark.

Final Thoughts on I Know What You Did Last Summer
I Know What You Did Last Summer is a film caught between ambitions—trying to honor the original franchise while carving out space for new characters, aiming for genuine horror while leaning on nostalgic callbacks. It's not a complete failure, and it's certainly not the worst slasher sequel you could watch (the bar set by I Still Know What You Did Last Summer is, frankly, pretty low). But it doesn't quite stick the landing, and audiences seem to sense that. If you're a completist who needs to see every entry in the franchise, or if you've got a soft spot for summer-set horror, it's worth a stream on Prime Video. Everyone else might want to revisit the 1997 original instead.
