I haven't yet read the books (they're in the queue, but I'm currently going through Peter Hamilton's Commonwealth Saga/Universe[0] first)... but the show was both really interesting and really awful, imo. It had a good premise initially, the bit about mathematical formulae that can guide humanity through existential struggle, and then it just kinda dropped the ball on that concept beyond a few scenes. The show apparently introduced a concept not really emphasized in the books, according to others I've talked to, in the form of "Empire" - a singular man, cloned multiple times, with a youth version (Dawn), an adult version (Day), and an elderly version (Dusk), some of which overlap beyond just the 3 generations. That was one of the more interesting bits of the TV series to me, since the rest was somewhat muddled and incoherently presented. Acting ranged from decent to awful. Too much mystery building for a show with no guarantee of a renewal. Worth a shot if you're bored and into SF though.
