We all knew the foundation from which this show was launched. Some expected BSG part 2, while others were hoping for an entirely new show with an entirely new identity. Happily, the latter were correct.
Caprica originally took for granted its setting, in a SciFi universe we had all grown to love. Eventually, after a few episodes, Caprica began to create its own identity. It wasn't until episode 5, when the plotline started to focus on the virtual, or V-World, that the show grew its own wings.
What we had after this was a new universe within an established dogma. I cannot imagine that this is an easy feat.
I will admit that the events of the midseason finale were interesting, although not mind-numbing. However, this seems to be a slow-burn type of a show. If you can remember so far back, BSG was very much a slow-burn show.
All of the elements of success are present here; we're just waiting for them to exert themselves.
