The jaw-dropping science documentary Cosmos: A Spacetime Odyssey [$53.98] and follow-up to the 1980 television series Cosmos: A Personal Voyage, which was presented by Carl Sagan on the PBS and is considered a milestone for scientific documentaries. This series was developed to bring back the foundation of science to network television at the height of other scientific-based television series and films. The show is presented by astrophysicist Neil deGrasse Tyson, who was inspired by Sagan as a young college student. Among the executive producers are Seth MacFarlane, whose clout and financial investment was instrumental in bringing the show to broadcast television, and Ann Druyan, Sagan’s widow and a co-creator of the original series.
