Watch your back! Cupid will be on the prowl this Valentine's Day weekend, hunting down potential targets to unleash a volley of amorous arrows onto unsuspecting mortals. Our modern candy and roses-centric celebration of Valentine's Day has deep roots that date back to the ancient pagan fertility festival of Lupercalia. These days it's a much tamer affair with red-and-pink greeting cards and over-priced flowers instead of ritual sacrifices providing the celebration's dominant crimson-hued colors.
In honor of this chocolate-dipped occasion, we've gathered a sentimental collection of science fiction television series to binge on Saturday that include UFOs, time-travelers, sentient spaceships, caped superheroes, mental telepathy, alien love, and futuristic matchmaking.
