Lack of fan base? Not as popular? This has to be the most uninformed post on the topic, I have seen in years. BSG was a ratings hit in it's first season. And keep in mind, this was on a broadcast network (ABC). To give you a ballpark figure, that's roughly 5+ times the viewership of a cable network.
Its really simple math. To make nBSG a hit, all they had to do was get half the fans of BSG (4m) to watch it. If just half of them (2m) liked it, you're a hit (on a cable network). And that is exactly what happened.
Moore's version didn't just "end". Its over, story complete, with little to no interest, for future endeavors of the version. The same cannot be said of BSG.
That is why we are discussing the reboot of BSG in the TOS forum.
I would have thought that with the traction that the new Star Trek has had and the upcoming new Star Wars movies, Battlestar would be a no-brainer, but Universal's movie division is a mess and when they're making films like Battleship, I really wouldn't want them to touch the show with a 10 metron pole.
BG is a very expensive fim or TV series to make even with CGI. Part of the reason that the last series didn't go to five seasons as originally planeed was due to spiralling costs.
The thing is, they've made money in the past with THREE BG movies in theatres, sure two thirds of that was in foreign markets, but you don't release two other movies if the first one hasn't made a profit.
As to those wanting a BG film based on the third series, do they know that Glen Larson stipulated when selling the rights that no one who worked on that version of the property can work on a movie version.
