I Know What You Did Last Summer started out with a lot of potential. It was gritty, high-stakes, and twisted up people into versions of themselves they never knew were possible. And at that time, when we were still innocent, we hoped that Alison would find the kind of person she wanted to be for herself. Instead, what we got is a young woman who became her sister, from top to bottom.
And it makes you wonder, who is Alison? Have we even seen her? Because all we got is her angsting in the beginning and then being a douche like her sister always was. We never got a chance to see the real her and what she was capable of. Even after legit being stabbed, she chose to continue acting like Lennon because we think she’s so terrified of actually looking in the mirror and seeing herself. And that doesn’t make for good storytelling.
The same thing goes for Margot. Really, she was the killer? Pass. In stories like I Know What You Did Last Summer, you’re supposed to have at least a little sympathy for the killer in question. There was none of that with Margot. She was just a delusional young woman who let those delusions get the best of her while and who got angry when things didn’t go her way. That doesn’t make a compelling villain.
Instead, when it was revealed that Margot was the killer, we were bored. We became even more bored when the post-credits scene showed Margot vlogging about how she got away with everything. Storytelling like that never works. If anything, it’s sloppy and goes the route of telling us what happened instead of showing us. It’s a classic mistake in storytelling that could’ve been solved with more episodes and a better reveal.

Then there’s the Dylan of it all. By no way, shape, or form do we like him. But he’s had the short end of the stick given to him over and over again. This time around the girl that he loved and that he just had sex with (while said girl was pretending to be her twin sister) threw him away like week ol’ garbage, proving she never cared for him, his love, how he felt, or what this would mean for him.
Alison destroyed him. And knowing that she chose a killer over the boy she was in love with…it feels weird. Yes, Alison had feelings for Margot, but she just stabbed you in the gut. We’re pretty sure that no one is going to believe her when she says that Alison took Margot’s place. Plus, again, you were stabbed in the gut. That’s not something you forgive while promising to stay with that person forever.
Oh, we can’t do a I Know What You Did Last Summer review without talking about another batshit crazy thing that happened…Riley waking up. What in the actual hell was that? First of all, how was she in a standing position? Secondly, no one decided to check her pulse? Thirdly, no one noticed her breathing? And lastly, pretty sure that you can’t just open your eyes like that after being covered in sticky AF honey.
It’s just a hot mess that started out fun but lost it’s way before things got really juicy. And it’s a damn shame.
