When prequels (I hope that is how you spell it) are done well I do feel they can be successful. The Star Wars prequels and Star Trek: Enterprise are bad examples because they were done poorly.
So I do disagree with Sean’s statement that doing a Battlestar Galactica prequel is like doing a show on the history of Alderaan because if done well they can be good and entertaining stories.
Example, before I tuned into the new BSG I knew that the 12 Colonies were going to destroyed by the Cylon machines and that the only surviving Battlestar would be named Galactica, and a chance that a Battlestar named Pegasus might also survive… Funny, I think the mini-series was some of their best work to date.
So I won’t write it off without giving it a chance, but then again it doesn’t look like something I would watch.
