Oh no, not again.
So, after the fuss over the phenomenally bad idea of making a "reimagined" Buffy film in an attempt to cash in on the fans of the TV series, but not using anyone or anything from the TV series at all, they're now trying to do exactly the same with BSG? Clue: the TV series of Buffy and the new BSG were popular because they were good, not because the original on which they were based was somehow guaranteed to drag in a lot of people. At best, the tie-in to the original BtVS or BSG would make people read a review.
Since both reimaginings were vastly more popular than the originals, any attempt to ignore them is going to make fans keep away - these fans being those who were intrigued by the hook to the original the first time round. It's like making a Spider Man film based on the comic series and ignoring the recent films, or making a Batman based solely on the Adam West version (not that this doesn't have its place in history).
Still, at least this time the people involved weren't directly responsible for the original being less good than it could have been. I'm not sure that the fan disappointment at the ending of BSG (TNG) is going to make them come and see this, though.
Now, how about a film of Veronica Mars? A Buffy film actually set after Chosen, in Whedon's Buffyverse? (Even getting Summer Glau to do Fray?) Tie T:tSSC into a Terminator film?
Sadly, I'm betting on Friends: The Movie happening first.
