I've watched the first 6 episodes so far. I think the story line is good and the casting is fab. I think the show explores a lot of social restrictions and thinking from this era in an accurate way. The story of Jack Parsons is an interesting one, and it works well as a TV series.
It's not heavy on shock value (lazy writing) which could have been a problem with the topics of occult and sex parties. I think the pace is a little slower than I would like but it's acceptable. Surprised by the low rating as this show is definitely higher quality than most of the stuff that is out there. Most comments are favorable.
