Agar comes from multiple sources, as many red seaweeds are “agarophytes” (that is, seaweeds containing agar in their cell walls). Species of Gelidium are the most important source of bacteriological (lab-grade) agar. Other main agarophytes, largely used for culinary agar, include red seaweeds from the genera Gracilaria, Pterocladia, Ahnfeltia, and others. Species from the genera Eucheuma, Gigartina, and Chondrus have been used as agarophytes in research during agar shortages.9
While Stanton collected a promising cast for his film, the reviews out of its Sundance debut were bleak. And we can confirm, this movie is a mess. Imagine Black Mirror without nuance or Cloud Atlas without ambition, and you'll have some idea. The Neanderthal plot, which features no modern dialogue, is the most impactful thread. The rest is confounding and bland. — Kristy Puchko, Entertainment Editor
