I'm extremely surprised at some of the poor reviews. I'm only a few episodes in and decided to see what others have to say, but trying not to read too much as I want to avoid spoilers. The acting is superb and for me, with such a dramatic show, that's key. I don't care if the whole NASA space trip to Mars is accurate to what real life would be like (think Ad Astra), im not a rocket scientist with any experience level of engineering or physics, so all of that backdrop works for me. This is a show about love loyally and trust and so much more. Maybe I'll change my view when I'm finished, but so far, I'm really digging it.
