If you want to see some bitter fans of the original series, read the boards at cylon.org. Damn, these people only watch the show so they can bitch about it. One guy even says it outright.
That sounds like some people on these forums about the prequels. But I digress.
I was a fan of the Original BSG when I was a kid, and I'm a fan of the new one....but I don't try to compare them for a second...the new series is a complete re-imagination of the story, and I like what they're doing so far.
