Finnaly a show to look forward to every week.
SGU is what Caprica should have been about: Space, Internal conflicts and Space again.
Why would a family drama set on
Caprica called
Caprica be about or set in space?
"It's on a need-to-know basis. And you don't need to know."
In other words, you got nothing. It doesn't make any sense anyway that Caprica should be anything like SGU.
• Stargate Universe is set on a *very cool looking* space ship. Caprica is not.
• Stargate Universe is set in contemporary times with people from familiar cultures. Caprica is set 150,000 years in the past, on another planet, with an alien culture that is only superficially (or mockingly) similar to our own.
• Stargate Universe is based on a space travel theme. Caprica is decidedly not.
The two are no more the same than Caprica is like Eureka, or Caprica is like Rome (the show that it's actually the most like), or Caprica is like LOST. Whether you like the show or not, it has carved out its own niche. Both have strengths and both have some serious weaknesses.
All that said, I don't mind getting my occasional space-adventure fix from SGU either, since I doubt I'll ever get that from Caprica (nor do I necessarily want to). I miss my spaceships damn it! I like SGU and Caprica, because they both give me things the other lacks.
When it comes to genre shows, I'm no specialist. I'm a generalist and like to have a balanced diet. SGU for the space exploration stuff, Caprica for the speculative future stuff, Fringe for the X-File'ish mutant/"truth is out there" stuff, Supernatural for the mystical, demon-killing stuff, Doctor Who for the really ridiculous, over-the-top, sci-fantasy stuff, LOST for the...

...well whatever stuff LOST does and so on.
I keep a well stocked pantry; no crap. I'm discriminating, but not finicky. No, everything is not of
equal quality and there are some off brands, but I like knowing it is there when I go looking for it. We are, after all, in what has to be one of the most prolific periods in history for genre television. Almost 1/2 dozen more will premier sometime this year. We even
finally have another spaceship based exploration* series, seemingly eons after Farscape, Enterprise and other similar shows went off the air.
Great time to be a genre fan.

= This is one aspect that I think should be preserved from the Stargate pantheon in Universe, as I believe you can have an intelligent, more mature spaceship based drama without going the "no aliens", quasi-Luddite route of Moore's BSG or Whedon's Firefly. Outside of the big-bads, SG has always had rather ingenious aliens and that's a tradition that the "wrong people" motif doesn't necessarily need to clash with. Keep them nuanced, realistic, varied and (most importantly) scarce and you'll do fine.
