You're confusing Dirk with Richard Hatch, who was the original Apollo. He originally criticized the show and then they cast him -- inspired casting, IMHO. Chances are slim Benedict will do the same.
Well they didn't quite just "cast" him like to shut him up. They approached him, from what I've read, more as a peace offering. Aknowledging they were doing this with BSG other than he wanted but they were still respecting the roots. And I think they are. The original was building towards a lot of interesting discussion on morality and the soul, and the re-make has dug right into there.
I'm not with Dirk on the idea that there's moral ambiguity in the new show. Yes the Cylons think they're doing the right thing, but that's the nature of the world. People don't think they're evil, even the most evil people in the world (barring outright nutjobs) think what they're doing is right.
I'm also not with him on the characterization of the male characters. Adama isn't weak and has no trouble making decisions, same with the XO and most of the others. Now Lee/Apollo has trouble making decisions, but he's the classic character who's situation has outstripped his moral certainty, he wants to do the right thing but is now in so far over his head in life that he's generally not sure what the right thing is, and the situation has gotten severe enough for him that even things he used to be certain of he isn't anymore, happens to a lot of 20 somethings it's part of managing to avoid adulthood for too long.
Opps. My bad. I knew that the fellow they cast as Zarek was on the original show, and that he was bitterly opposed to the remake... until they cast him.
But, yeah, the new Battlestar is one of the best shows on television.
