Consider the sequel curse broken: Fear Street Part 3: 1666 satisfyingly wraps up Netflix’s R.L. Stine movie trilogy with deepened themes, more fully realized characters and enjoyable twists that lend dimension to the arching story.

Fear Street Part 3: 1666 isn’t just the best of the Netflix horror trilogy; it also recasts the prior two entries, “1994” and “1978,” in a more favorable light by deepening the mythology and underscoring just how crucial it is to watch all three chapters consecutively.

Fear Street Part 3 is an absolute blast. But there’s tragic darkness prevailing here, as there has been through the previous entries. Yes, we’re having a good time with all this horror, but we’re also affected by the senseless death and dismemberment. There is no reveling in the spilling of blood here. There’s just a unique feeling of loss; the sense of cosmic injustice at young lives being cruelly snuffed out by thoughtless, uncaring hands. It’s oddly beautiful in a devastating way.

1666 mostly operates in a different register than 1994 and 1978, but is no less entertaining. It rounds off an ambitious triptych chock-full of horror-history allusions, strong world-building, sharp scares, palatable gore, lively filmmaking and a likeable set of characters. Other scary-movie franchises take note.

Executed with the confidence of a victory lap, the last hour of "1666" is a series highlight, especially as it captures the brand of out-and-out fun that has made Janiak a newly minted crowd-pleaser in horror.
