However, It's far easier to identify with the BSG characters, because they're closer to real human beings than the characters in star trek ever were, or could be. Consistent and perpetual moral high ground that is ultimately always right with no grey areas?
Huh? I don't even need to quote DS9 (though it would so easy to do so) to shoot down this point. TNG Episodes: The Wounded, The First Duty, Ensign Ro, The Most Toys, Silicon Avatar, and The Pegasus. That's off the top of my head. There are plenty of TNG episodes that didn't present "consistent and perpetual moral high ground." Some of them raised tough questions (The Most Toys and Silicon Avatar, when is killing in self-defense justified?), some presented characters behaving like self-serving assholes (The First Duty, The Pegasus), others had moral ambiguity and unhappy endings (The Wounded).
And if it's a viewpoint character you're looking for, there's always Chief O'Brien. The rest of them weren't supposed to be viewpoint characters. The whole point to TNG was that these people are the best of the best, that was stated over and over in the show, they're supposed to be the people that you look up to, not people that you can see yourself as.
Incidentally, I really liked the BSG remake, but it came off the rails at the end with the religious/destiny nonsense that always made me reach for the fast forward button on my DVR. Not coincidentally, the Prophets subplot on DS9 was my least favorite part of that show.
