This Troi episode attempts to be a sci fi horror thriller but comes across as a convoluted yawner with poor special effects. There are some nice touches (the morgue scene with Dr. Crusher might have the creepiest moment in the history of Star Trek), but also a lack of energy and cohesion. (It didn't help that the episode originally ran nine minutes too long and had to have some pretty big pieces cut out of it for television.) While there are worse Troi episodes, there are certainly quite a few better ones as well.
