Netflix's original content library continues to grow and expand into new TV genres. The latest is Knights of Sidonia, an anime based off a manga about genetically-altered mech pilots fighting shapeshifting aliens. The series originally aired in Japan earlier this year, but now all 12 episodes of season one are set to hit Netflix everywhere it's available on July 4th. Netflix's version also features a new voice cast for the English dub, though a subtitled version will be available as well. Check out the trailer Netflix posted on YouTube today, which highlights the post-apocalyptic, space operatic nature of the show.
