Critic Reviews for I Know What You Did Last Summer
A third rate slasher franchise trying to be first rate. The best I can say is it is better than I Still Know, which is a very low bar for sure. This one did nothing for me, not one time was I in suspense and more often I was kind of bored. I didn't mind the twist as I couldn't care less about any of these characters, new or the two legacy returners in it to cash that paycheck, which I can't totally blame them tbh. Now, I will say I do have a crush on Chase Sui Wonders... **2.0/5**
FULL SPOILER-FREE REVIEW @ https://movieswetextedabout.com/i-know-what-you-did-last-summer-movie-review-a-hollow-scream-into-the-void/ "I Know What You Did Last Summer is a glossy, shallow reboot that mistakes recognition for resonance, failing to revitalize the franchise in any meaningful way. Despite a few solid performances and flashes of potential, the film never finds its footing as horror, legacy sequel, or even as a character-driven drama. It's not thrilling, it's not moving, and it's certainly not memorable. The only thing I know for sure is that I'll never revisit this summer." Rating: D-
Why? This is terrible. A group of spoilt youths congregate together to celebrate the nuptials of “Danica” (Madelyn Cline) with beefcake daddy’s boy “Teddy” (Tyriq Withers). They’ve had a few drinks and set off down the road to watch some fireworks; there is a raid accident; papa hushes everything up; one year on… The wedding plans have gone the way of the dodo. He has taken to his boat and the bottle. She has concluded that her erstwhile beau is a bit of a drip, and not being the let the grass grow type of woman, has now got engaged to someone else. With all now reassembled to give her gold, frankincense and myrrh, some old skinflint just gives her a card. Has it cash, plastic surgery vouchers, the script for the extended director’s cut? Nope. It’s a card - and it’s message is so foreboding as to cause them to fetch poor old “Teddy” from his stupor and relive the atrocities that visited their town of Southport in 1997. Luckily, veterans of that crime spree “Ray” (Freddie Prinze Jr) and “Julie” (Jennifer Love Hewitt) are still local and maybe they can help put. Well fairly swiftly, but by no means quickly enough, the body count starts to mount up. Unlike the rest of us, these folks are being hooked. Who is doing all of this and why? Maybe it was just sheer luck, but I guessed who was doing what to whom very early on, and I don’t think anyone would find that difficult. Thereafter it’s really quite a poor attempt at a slasher that is completely devoid of any sense of menace. As with many of the recent attempts to revitalise this genre, the characters are unlikeable and deserving of everything they get. Moreover, the scenarios are just plain silly. Just ask poor old “Milo” (Jonah Hauer-King) who goes wandering about outside (without even his shoes) whilst his lifelong buddies are dropping like flies. Almost all of the threat comes from it’s over-scoring and the only screaming going on is that which says “straight to video”. Very disappointing, sorry.

They've got the secret, and now the apprehension and distrust, it's time for the mayhem to begin. Had an interesting vibe going on, and then the killings begin. I definitely had some fun with them. I'm enjoying the twist of a look into the original murders by the next generation of social elites. Karma is going to make this fun, I'm hoping. I'm actually liking this fresh and new dealing with our vengeance killer. What a fun ride this fun had been. I had no clue I'd like it. Set up for future films is well in place...
