Well I just watched the very last episode and I've got to say that it was absolutely brilliant. Every credit to the writers, who effectively put the series to bed in great style.
The whole storyline came together, all loose ends were (effectively) tied up and the ending was indeed credible to the point whereupon (to my mind) it left the viewer with an alternative view to the origin of human evolution that perhaps even Charles Darwin would have contemplated.
Still sad to see the series come to an end though, sigh.......................!
Oh heck - I hope I'm not descended from Gaius Baltar!
Frakin hell!
