Warning Sign fails to deliver any substantive messages or any genuine thrills. Go to Full Review
Craig Schroeder Battleship Pretension Jan 7, 2021
In the war against the capitalist curation of streaming services, Scream Factory continues to be a noble soldier, offering horror fans the opportunity to see forgotten oddities and small pictures that would otherwise go unnoticed. Go to Full Review

A sedate endeavor. Go to Full Review
Tom Long Santa Cruz Sentinel Feb 4, 2019
The film is fast-paced, predictable, and ultimately mediocre, but at least it helps breed some healthy paranoia. Go to Full Review
Felix Vasquez Jr. Cinema Crazed Oct 15, 2018

Kylo Nov 10, 2018 This is something I would have expected to see on SyFy. Good cast, bad direction and laughable plot. I'm still wondering why it garnered an R rating. IMO it was barely a PG. See more
Theodore R May 26, 2018 This movie was cool for an 80s science fiction horror flick.
Mar 1, 2018 It enjoyed this movie as a young teen. I loved the biological aspects of it.
