Amazon’s addition to the cult classic franchise changed a few key elements from the 1973 book and 1997 film. The two most significant changes were modernizing the tale by adding social media and adding a dead twin to the mix.

The show starts with a party where all the main characters gather for one last night of freedom before graduation. But one argument between twins Allison and Lennon ends in disaster.

Peacock snatched the film rights to Karen M. McManus’s debut novel, One of Us Is Lying, and they did a fantastic job.

On the first day of school, Addy, Cooper, Bronwyn, and Nate are in detention with Simon. After streakers distract their teacher, Simon starts having an allergic reaction to something he drank. The rest of the episodes focus on the investigation by the group of suspects to clear their own names.

To be honest, once you’ve seen the 1997 I Know What You Did Last Summer film, you’ve seen all of the franchise. And that statement stands true with this show for the most part.

None of the characters were really likable, even when we’re supposed to be rooting for them. The only semi-likable character, Johnny, lasted two episodes before being killed off. The relationships felt a little too forced, specifically between Allison, Margot, and Dylan.

The cast was the best part of Amazon’s I Know What You Did Last Summer. I loved seeing a more diverse cast compared to the past franchise installments. And each cast member did so well in their roles that I look forward to seeing more of their work one day.

Another addition to the story was the twin aspect. I always love seeing twins switch places, and this was very reminiscent of The Lying Game series by Sara Shepard.

Based on our back-to-back watch-throughs of the shows, we had to give One of Us Is Lying credit because it made it really hard to finish I Know What You Did Last Summer.

We also think the casting for this show was just as perfect as I Know What You Did Last Summer. It was diverse, as that’s how the book was written. And we didn’t feel like any of the major characters were one-dimensional like some of the Last Summer characters felt.

I Know What You Did Last Summer was canceled in January. So, for those that want to know what happens when Riley woke up and Allison and Margot ran off to live life together, you’re a little out of luck for the rest of the story.

On the other hand, One of Us Is Lying is coming back for a season two at some point. Peacock renewed it around the same time Amazon canceled their show.
