I am ok with everything they did except that they left the Starbuck deal a little too ambiguous. The head six and Baltar thing wasn't truly explained either, although it was strongly suggested through Baltars words that they are "Angels".
I'm like most, the first hour and twenty minutes was the best of the series....the last 40 minutes....well....it was average. That still puts it heads and shoulders above everything else on TV right now.....but as far as the bar the show has set for itself....it was average.
