Sometimes, more is better!
Sometimes They Come Back... Again is a remake, more than it is a sequel, to the decent 1991 Sometimes They Come Back, adapted from a short story by Stephen King. In its best moments, this is a basic supernatural slasher. The body count is high, the make-up ambitious, and the effects generally better than the original. The script is well paced and denser.
The cast is composed of familiar faces. The leading antagonist, unlike his sidekicks, is played by a strong, unusual actor that inspires fear through facial gesture and mannerism. Protagonists are given flash backs, a religious procedural and occult hocus-pocus to deal with, converse about, while the good stuff happens elsewhere. Consequently, some subplots feel detached, unnecessary.
While some characters have a dramatic story arc, others are directed to play it slapstick and are treated like slasher cattle. Both moods work fine, but the contrast hurts continuity. This is released in a time of quick cuts and heavy reliance on post-production. Some effects are practical but then some are cheap CG. All in all, this one hits and misses but is more entertaining than the original.
