“Killer Concept” (*1/2 out of four) was an inept horror comedy about three friends (Cody Bishop, Coley Bryant, and Casey Dillard) who team up to write a screenplay about a series of gruesome murders in their town but they soon come to realize that one of them may be a murderer themselves and may be behind actual recent killings going on and is documenting this in their script. Potentially juicy and sharp material for a satire is undone by annoying characters and a limp screenplay. You could only imagine what a ruthless director like Christopher Guest or Woody Allen would have done with this material; this falls flat and turns out to be a “killer” mistake.
