“The Legend Of Halloween Jack” (* out of four) was a nearly worthless horror show that won’t develop much of a legend of its own; on Halloween eve, a serial killer (Lee Bane) who looks like a thrift-shop scarecrow returns from the dead to seek retribution from the vigilantes (led by Colin Holt) who killed him one year earlier. More scares may have ensued had he gone to Walmart instead. This scareless bore makes any of the maligned “Halloween” sequels look like masterpieces by comparison. Holt’s fine and intense performance is film’s sole asset.
