I watched the miniseries last night on DVD and I thought it was pretty good show. I do not however think it is better than the original. It may be nostalgia, but I prefer the original from 1978-9. There were a couple things that bother me about the retelling of Battlestar Galactica. The biggest is turning Starbuck into a woman and turning Boomer into a woman and a cylon.
In the original, Apollo, Starbuck, and Boomer were best friends, and would hang out together when off duty and always stuck up for each other. They were almost like the the Kirk, Spock, and McCoy trio of Battlestar. I'm not sure if there will be this same relationship now in the new series, especially with Boomer being a cylon. Whether she is an active cylon agent, or a sleeper, I'll be waiting for her to betray the colonials.
Other than that, I thought it was pretty good, except for the drum beating during the combat scense, which I thought was annoying, and the large number of make out scenes, especially between Baltar and number 6. I did think it was funny though when Cmdr Adama made the comment that people needed to start doing it, or something along those lines.
