David Crawford of the Radio Times criticized the first episode for its short length and "lightly sketched" coverage of science, but wrote that it is "full of arresting images".[3] A similar criticism was made by Jonathan Wright in The Guardian, who stated that the first episode is "far too short at 30 minutes and thus skims over some subjects".[4] Crawford writes that the fifth episode, like the first, "packs a lot of information into its short running time,"[5] and praised the final episode on Svalbard, likening it to a " mini-episode of Frozen Planet" filled with "jaw-dropping, eye-covering scenes".[6]The Guardian's Martin Skegg was more positive on the length of the final episode, writing that "relaying the complex interplay of life in just 30 minutes, the film is a punchy antidote to the sometimes bloated 'event' nature".[7]
