Well, first, I really don't think Star Trek (2009) is "angsty" or "gritty," so I wouldn't consider this an apples-to-apples comparison.
Second, the BSG miniseries was so depressing and hopeless, I just couldn't get on board. I really tried to like the first season, but it was too depressing to continue watching.
So, they're not similar. I love Star Trek (2009). I've watched it four times, and each time I see the movie, I want to go right back into the theater and watch it again. For me, it's that much fun.
