So, first of all, I must say it's obvious SciFi (or is it SyFy now?) put a shitload of money into Caprica. The visual effects were awesome, the highlight being the Cylon Centurion. It looked better than some of the robots in Star wars Ep III.
But other than that, I wasn't really all that impressed. I knew it would be more of a drama that happens to be about robots than a robot show that happens to be dramatic, but still, it seemed a bit boring. Clearly, the main conflict is about what it means to be human. Is Zoe Graystone's digital image the same as the real thing? Is it a good idea to make AI robots? Why should we be better than the robots if we do the same evil things? All these questions have already been the subject of other, better works of fiction. Mainly BSG itself, and the great, wonderful, astonishing Blade Runner. So what is different about Caprica? There seem to be two other plot lines going on. Zoe and her friends were part of a religious group worshiping what sounds like the God the Cylons worshiped. I think that's pretty cool, because now that Zoe is part of a Centurion, they clearly took that idea of a God from her. The other thing is that Joseph "Adams" (apparently he changed his name from Adama to Adams, because he's from Tauron and he wanted a new beginning on Caprica, away from his peasant heritage) is not the glorified lawyer BSG made him out to be. He has ties to Tauronian mafia (BTW, the Taurons are apparently all Hispanic) and those guys have some sort of leverage over him (forgot what it was).
Also, I'm not so sure Caprica works well in the BSG universe. Some things I found odd:
-Joseph "Adams" is a bit of a crook
-the Adama clan is from Tauron... I always thought the old man was Caprican to the bone. Was this ever mentioned on the show?
-if this is almost sixty years before The Fall, then how old was Galactica? They have all this super cool technology in the movie, yet Galactica looks like a World War II submarine. I know it's supposed to be an old Battlestar that was ready for retirement, but now it looks REALLY old in comparison.
-the setting is 58 years before The Fall. Billy Adama is eleven. Am I really supposed to believe Admiral Adama was 69?! E.J.Olmos was 57 when BSG started.
but there were cool things as well:
-while I found the idea of virtual reality being so important a bit strange, at least the V Club was shot in the same theater as the Opera House stuff from BSG and I thought that was pretty neat
-speaking of virtual reality, is this where the Cylons got the idea of projection? because Zoe Graystone was into the VR stuff? Cool.
-Daniel Graystone owns the Pyramid team Anders played for! And we got to see their stadium!
-despite the robots and virtual reality, this "future" was pretty realistic and Earth-like, which I think makes it more believable
And remember when I mentioned Blade Runner?
William B. Davis (famous from The X-Files) had a small part in Caprica playing some sort of politicians, and he had THE EXACT SAME glasses as one fo the characters from Blade Runner. Check it out:

Blade Runner:

It's really just an obscure nod from the writers, who I think had no choice but to acknowledge the fact that the premises of Caprica and Blade Runner have several similarities. If you're not a fan of Blade Runner, you won't even know, but I know the movie by heart so I'm going to constantly compared the two. Guess which on is inevitably going to win...
Overal, it was a nice character-driven story that works if you don't know BSG better than if you're a fan. Which is weird because it's a prequel. (The time discrepancy was just too distracting.) I'm going to watch the show next year because there probably won't be anything better (besides Lost), but I don't think it will be a smashing hit like BSG.
