Todd Gaines’s review published on Letterboxd:
Fear Street Part Three: 1666 does have a fitting conclusion, but I still miss the frantic energy from Part One.
If you like witches and music that sounds like Riverdance or an episode of Outlander, you should be jamming to the first act of 1666. I also believe if you enjoyed the overall pace and story of 1978, there is a great chance 1666 will be your favorite film of the trilogy.
While 1666 is not a full-blown slasher, I believe I enjoyed it as much as I could. My biggest takeaway is: We need to adapt more R.L. Stine novels into movies.
