Halfway through the first episode before i had to go to sleep. I personally love it, but I think a lot of the info seems rushed for the average person. Like a lot of statements of "this is the way it is" without digging deeper into how we know that (the math, the physics, etc.)
Of course, lets be real the only people watching this show are people who already have a love for science and astronomy so it really doesn't matter in the end. And perhaps the next episodes will flesh out the ideas more, this could have possibly just been an introductory/overview type of episode
