The only hope for someone to enjoy Night Skies is if they read the box and return it to the shelf. In pursuing this simple course of action the viewer - regardless of how generous a viewer they may be - will have saved themselves an hour and a half of abysmal script, perfunctory storyline, questionable special effects and poor sound work. It seems incredible that in a time when special effects are in their hey day that even a low budget movie could handle them with such a complete lack of skill.
Briefly - the Phoenix Lights appeared on March 13th, 1997 over the skies along the line between Phoenix and Tucson and were observed by thousands of people. In the end after some investigation it turned out the lights were nothing more than slow burn/slow drop flares released by an A10 Warthog over Luke Air Force Base during a training mission. If only someone had let the facts get in the way of the story. A documentary about slow burn flares would have been more interesting than what the "writers" of this movie did with the UFO myths that have sprung up around the Phoenix Lights.
We pick up the action with two couples and a fifth wheel friend navigating their RV through Arizona - naturally enough they are lost. After a road accident caused in part by the lights and mostly by stupidity one of their number is badly injured. A mysterious stranger - with military training and a history of substance abuse - comes to their aid after which things start to go weird. By weird it should be understood that every formulaic cliche that you have seen in a horror or SF movie is trotted out to string along a story that should have died before it was pitched.
Save yourself the time and the money and give Night Skies a pass.
