The employees of a cult-like biotech start-up test their product on themselves. “Aquaculture” is a (slightly) sci-fi satire about the grandiose vision of a quietly eccentric entrepreneur. Freely mixing absurdity and sincerity, it’s a strangely engrossing film filled with mystery and restraint. Written and directed by Artemis Shaw. Starring Josephine Decker, Nicole Chaffin, Abigail Wahl and Jacob Nichols.
