Keith Adams Jr.’s review published on Letterboxd:
It’s the 3rd week of July and Netflix’s 3-week, 3-part movie event comes to a thrilling conclusion in a final chapter where the fate of Shadyside’s future lies in the past! After connecting with a grownup Ziggy (Gillian Jacobs) to find out more about the Fier curse, Deena (Kiana Madeira) & Josh (Benjamin Flores Jr.) discover more secrets that could be the key to lifting the curse and the biggest secret lies in Shadyside circa 1666, where young Sarah Fier (Madeira) has a forbidden romance with the pastor’s daughter Hannah Miller (Olivia Scott Welch) but that’s not what starts the curse. What starts the curse is a series of unfortunate events that plague the town, from the food going rotten to the animals behaving violently and it culminates with Pastor Cyrus Miller going mad, holding some townspeople captive in the chapel and murdering them before he himself is killed by Solomon Goode (Ashley Zukerman), the descendant of Sheriff Nick Goode and at a town meeting, Solomon’s brother/Mayor Will Goode’s descendant Elijah (Matthew Zuk) accuse Sarah & Hannah of witchcraft after they both dismiss his advances and while Hannah manages to escape death with Sarah’s help, Sarah isn’t so lucky as she’s found, attacked, has her hand sliced off and hung but not before placing the curse on the town. Who was the target of Sarah’s ire that led to the curse and can it broken once and for all? Part 1 delivered the ‘90s slasher vibes and part 2 brought the ‘70s summer camp horror style and now, this final installment finishes strong with a blend of witchcraft melodrama and the supernatural slasher thrills of the first film is able to connect every dot without it feeling convoluted or messy. The best part of all is while things do wrap up, the ending does set up a potential second trilogy of films and if that happens, I’d be all in for it. Just picture it: “The Ghosts of Fear Street”. Got a nice ring to it, don’t it? Fear Street Part Three: 1666 is a solid and entertaining conclusion to a supremely entertaining horror trilogy and leaves the door open for more stories from Shadyside. Leigh Janiak, I do hope you make a second trilogy.
