I think RH written many novels on the TOS BSG universe and deeply entrenched in how TOS was. And it is hard for him to be willing to brek from some of the visual styles and concepts. That’s why RDM and the gang can take the show to the next level and RH couldn’t.
But without Richard Hatch’s efforts to revive BSG, there never would have been our new series. And like some one mentioned, a lot of early concepts of how the universe is like was already there in RH’s version.
It is kind of sad that new BSG doesn’t get high Nielsen ratings. Thus making it hard to justify the budget (hence a lot less massive space combat). That was essentially why TOS BSG was canceled and why it took so long to bring it back.
Yeah, I know the fans of BSG TiVos and watch through other forms of media. But still… had people watching it actually show up on Nielsen, I think not only the show would have been even better, we would get a lot more ground breaking shows to follow.
