Yeah I agree with you. A second reboot of BSG is just unnecessary. The first reboot was almost perfect (except for some of the subplot conclusions, which they botched).
And yes, there are so many other good intellectual properties out there. But not just ones they already own, but many other ones where a screen adaptation hasn't yet been attempted. For example Gateway, and Hyperion. Both of those were planned by someone but they've never materialized. And there's also William Gibson's entire Sprawl series, which would be very cool to see on a screen.
