Dirk Lester’s review published on Letterboxd:
Obviously, this could all only apply to me, but when I woke up this morning, I honestly did not expect my day to include another fun, militantly retro, teen horror outing courtesy of Leigh Janiak that this time was part adaptation but mostly an allegory rich homage-mashup of Michael Reeves overripe but bleak cult classic Witchfinder General and Joel Schumacher’s wantonly meta fang fest The Lost Boys. Now, I have to say that as with parts One and Two the director’s reach somewhat exceeds her grasp, as the various subgenre tributes in question are occasionally in the air rather than in hand and the resource limitations of the improbably ambitious production show … But for my money if there are going to be problems in one of these, that should be the list. So yes, Fear Street Part Three: 1666 has issues but it also has an engaged engaging cast, plus a few turns and slights of hand worth being sat down in front of up its sleeve. Not really sure what more I could have asked for from something like this.
