The most beautiful space documentary ever! I stumbeled over some clips of cosmos on the NationalGeographic YT channel, I got very curious so I did take a look & awwww man - this is one incredible show. [10/10] It has the most stunning animations 3D and 2D - just a freaking eye candy! [09/10] The direction & camera work is superb [09/10] Narration & moderation by Neil deGrasse Tyson is like honey for your ears, I feel like I'm back in kindergarten listening to a history lesson ^_^ [10/10] And the music - awwww man the music ... takes me right back to "Contact (1997)". You know why? Because it's created by the same composer: "Alan Silvestri" the master of "Back to the future", "Predator", "Avengers", ... If you are a soundtrack geek - this is a MUST HEAR! I was moved, I was inspired, it made me wonder & joyful. In 1x07 they even put the oil industry in the pillory (on FOX!). This show is informative, engaging, & literally amazing. ENJOY!


Totally brilliant. Makes the complex and wondrous easy understand with simple context. Having watched each episode of this show I was left feeling somewhat 'small' in the grand scheme of things. Whilst we like to think that things re in our control when all is said and done no-one here on earth has any control at all; the Cosmos has a way of surprising you!


This is my favorite tv show ever. Will never forget this.


This is such a magnificent series, explaining difficult concepts like evolution to both interested and to stubborn people. I hope it succeeds in opening up the minds of people to the wondrous world of science.


An amazing series following the footsteps of Carl Sagan's Cosmos! An interesting and inspiring documentary that I would recommend to everyone! I really hope there will be a season 2 and then more to follow!



The most interesting serial all time!


This is an amazing series. I haven't been this excited to watch a show since Mythbusters. It kept my 12 and 8 year olds amazed and they actually learned.


As awesome as it can be!


Significant content astonishingly presented in a a concise and cohesive way. A must-see series to all thoughtful viewers!
