AndrewC’s review published on Letterboxd:
The highly impressive Fear Street trilogy closes off with a terrific conclusion in Part Three: 1666 that manages to satisfyingly tie up the sprawling story and deliver yet another engaging film that I absolutely loved. This one's more of a supernatural horror film than the slasher that the previous two were, but it still delivers plenty of bloody goodness while balancing the story set up in its predecessors, seamlessly weaving the overarching plot into an ending that works wonderfully. There's also plenty of heart in the film that really gives it an extra boost, something that comes as a result of how well the two prior movies managed to set up its characters and invest us into the story. This is yet another testament to how thoroughly impressed I've been with the trilogy as a whole, a massive success in my eyes for Netflix, the writers, the cast, and director Leigh Janiak given how well they've been able to handle this tricky three-film concept and still managing to stick the landing in a satisfying way. I'd still say that I slightly prefer Part Two to this just because of how fun 1978 was, but Fear Street Part Three: 1666 is still a fantastic end to a trilogy that has become an instant favourite for me.
