Spoiler-Free Review of “I Know What You Did Last Summer” (2021) on Prime Video: A Re-imagining Done Right

*This is a spoiler-free review so feel free to read on!*

“You can never really know anyone…least of all yourself.”

I Know What You Did Last Summer premiered on Prime Video on October 15th 2021. The teen horror drama series (based on the Lois Duncan novel and the iconic film series) stars Madison Iseman, Brianne Tju, Ezekiel Goodman, Ashley Moore and Bill Heck. There are four episodes in season one available to stream now. The remaining four episodes will air weekly. Each episode runs for approximately 45-48 minutes.

After a fatal accident, a group of friends are stalked by a killer one year later, causing secrets to emerge and friendships to be tested.

Here is the trailer:

I Know What You Did Last Summer is the series I have been waiting for. It gives us some welcomed nostalgia for the original film series while finding a voice of its own, but is it worthy of YOUR next binge-watch? Let’s find out…

The Pros:

A solid twist on the original.

I’ve seen plenty of reboots and adaptations of films and I didn’t really know what I was going to get with this series, but I was pleasantly surprised by the twist thrown our way. There will be no spoilers in this review, but I thought that this show channeled the original vibe of one of my favorite films while finding a unique voice of its own.

You don’t mess with the original and this series understands that. Rather, it takes a new approach and a new setting to keep us entertained and it was the right call.

I also love that the series sprinkles in some Cruel Intentions and Cruel Summer vibes as well to give this series an edge.

Plenty of gore to satisfy the slasher fans.

The teen series takes a page out of Slasher’s book and presents us with plenty of gore and nudity galore. I’m not sure it needed all of that, but the gory kills are pretty solid and it helps balance out a lot of the teen melodrama you can expect in this type of show.

The Cons:

The killer needs to toy with them more…

I appreciate that this series is finding its own way with a different story, but if we are going to put up a message on a mirror, then I would also like to see the killer really mess with the group more. So far we have seen some horrific kills and some text messages pop up, but I want more.

Part of what made the original film so terrifying for me was the way that the killer lurked around and made the characters question everything and everyone around them. Someone already chopped off their hair without the killer’s help and while the pilot episode makes an attempt at this, I think that it could really add to the vibe of the show without copying the original film too much.

I also think that the characters seem to cope really easily with the death of those around them. I want to connect to all of them and it sometimes makes them come off as completely heartless, but I think that some of them are going to end up showing true remorse so I’ll see how this plays out in the next four episodes.

So am I in or out?

I’m in!

I was genuinely impressed at how well this show executed everything. The twist worked and it really helped me connect to this show. It balanced the perfect amount of nostalgia from the original film while presenting us with something new and really addicting!

There are some rough edges to work through, but overall this is a really entertaining series and it is delivering with plenty of gore, twists, and reveals.
