Really, really strong followup from the creators of Game of Thrones.
I worry that it might be getting a bit of a bad rap because people who've read the books are so obsessive about it (my own post in PTP is notably over the top).
But it really is an exceptional story, a friends drama that turns into a mystery thriller that turns into probably the weirdest (but also one of the most realistic) science fiction stories you've ever seen.
The first few episodes lag a bit, but episodes 5-8 are dynamite! If they get the money for season 2 (which is sadly not a sure thing quite yet) it'll get even better, with some mind-blowing philosophy and the biggest and wildest space battle ever put to screen.
