The last time J.M Dillard tried to mix Star Trek with horror, it didn’t turn out so hot. The idea scored some points for novelty, but the execution was lacking. But if at first you don’t succeed, so the saying try again, and in this case, the second time’s the charm. Now, just in time for Christmas ’87 comes a good old-fashioned Halloween yarn. Though the premise—”what if vampires, but Star Trek”—could have easily succumbed to risible goofiness, Dillard never allowed it to dominate the story and fortified it with some of her best character work yet. This week, we check out Bloodthirst, or, Porphyria and Loathing in Las Tanis.
