What This Means For I Know What You Did Last Summer
M3GAN 2.0 Performed Better With Both Critics And Audiences
The fact thatI Know What You Did Last Summerwas able to outgrossM3GAN 2.0was not a given, considering the fact that the latter title received much better reviews. While both received splats on Rotten Tomatoes,M3GAN 2.0earned a far superior 57%, compared toIKWYDLS' 37%.
These negative reviews of the new slasher include one fromScreenRant’s own Mary Kassel, whogave it a score of 4 out of 10. Below, read an excerpt from theirI Know What You Did Last Summerreview:
There are moments when the film is genuinely funny, and even a little sweet, but the stakes are too low and nebulous to be anxious about who will be gutted next. The film’s last-minute twist didn’t do anything to make up for this, as even if you didn’t see the killer’s reveal coming, it isn’t surprising. I never found myself genuinely wondering who the murderer was, which isn’t a good sign. I Know What You Did Last Summer isn’t the worst long-awaited horror sequel ever put to screen, but it doesn’t try to be anything but a shallow reflection of its predecessor.
The movie’s Popcornmeter scores show thatthey had a similar disparity of impact on audiences. Verified user reviews gaveI Know What You Did Last Summera score of 68%, compared toM3GAN 2.0’s 82%.
However,M3GAN 2.0’s Tomatometer score saw it taking a downturn from the originalM3GAN(93%), whileI Know What You Did Last Summerwas about par with the 1997 original(47%) and improved upon its 1998 sequel (10%), so this factor may have helped it achieve better audience retention by not provoking as strong of a negative reaction.
Our Take On The I Know What You Did Last Summer Milestone
The Franchise’s Future Is Still Murky
While theending ofI Know What You Did Last Summerteases a potential sequel, it remains to be seen if its worldwide gross ends up being high enough to earn one.Movies typically need to earn back two and a half times their production budgets in theaters, which could mean that the sequel is now in the black.
However, the fact thatI Know What You Did Last Summerhas only now surpassedM3GAN 2.0(which will most likely end up being a flop due to its higher reported budget of roughly $25 million) domestically may not instill enough faith in the franchise for it to continue any time soon, especially in the wake of its franchise-low opening weekend.
