I have seen the OG, 1997 I Know What You Did Last Summer, starring Jennifer Love Hewitt (Julie James), Freddie Prinze Jr. (Ray), Sarah Michelle Gellar (Helen Shivers) and Ryan Phillippe (Whatsisname). It came out a year after Scream, intent on capitalizing on that stunner's success; IKWYDLS was a decent slasher but not nearly as good as Scream. And so when I learned that they'd done a new installment in the series (the 1997 one, 1998's I Still Know What You Did Last Summer, 2006's I'll Always Know What You Did Last Summer (which I definitely did not see)), I was like, oh, is that still a thing? And yet, as far as decent series with diminishing returns goes, this most recent I Know holds up okay.
In 2024, Ava returns to her hometown of Southport, South Carolina, for her BFF Danica's engagement party. Also there are members of her high school clique: Danica's fiance Teddy and Ava's ex Milo, plus Stevie, a townie who never got to leave Southport to go to college. It's July 4th and the five decide to drive up to "Reaper's Corner," a cliffside road above the South Carolina coast (with those rocky cliffs, that's definitely not SC's coast). Goofing around, a little high on booze and weed, they cause a truck to go over the side of the cliff. Teddy convinces everyone not to tell what happened and they all go about their separate ways with varying degrees of guilt.
One year later, Ava is back in town for Danica's bridal shower: different fiance, as Teddy got really weird after the accident. Then Danica gets an anonymous note - I KNOW WHAT YOU DID LAST SUMMER - and the bodies start stacking up like cordwood. In over her head, Ava learns that back in 1997, there was another serial killer killing people in Southport: she does some digging and tracks down SPOILER Julie James (JLH, reprising her role from the first two movies). Also still in town is Ray (FPJr.) and SPOILER SPOILER SPOILER the vampire slayer herself, SMG, reprises her role of long-deceased Croaker Queen Helen Shivers.
The body count is decent (I counted seven); the Final Girl(s) acquit themselves well. And the ending SPOILER SPOILER sets up yet another movie with Julie James at the center. Good for you, JLH! I Know What You Did Last Summer is a perfectly adequate slasher that I found entertaining, with a splash of late 90s nostalgia thrown in for good measure. I didn't find it scary - I don't seem to be finding many of these movies scary these days, which either says something about the movies I'm selecting or my current unease with the state of the workd - but I certainly didn't regret watching it.
