This is one of the poorer episodes from the 7th season. The plots revolves around telepathic abilities, one of my least favorite aspects of the Star Trek universe. I like my science fiction at least somewhat grounded in science rather than pseudo-science. I grudgingly accept Troi's abilities when presented as extremely sharp intuition but when presented more like a true psychic ability I can't help but be skeptical. The plot is something of a who-done-it. I don't want to discuss the details because they aren't very interesting. But I can say that the ending is poorly scripted. The first time I saw the episode I didn't even fully understand how much of the episode the "reveal" covered... almost the whole thing.
