At the time the original series was being broadcast, I did not think it was cheesy. Now, yes. Then I remember that the state of Visual Effects back then was a whole bunch less capable than it is today. The original series had 2 things going against it from a production standpoint: the state of F/X, and most importantly Budget. Back then SciFi based TV productions were allocated very low budgets. It wasn't until Star Wars that the attitudes of the studios began to change towards Science Fiction budgeting.
I read up on the concept for the new BG and I was willing to give it a chance. I was not disappointed.
357, you need to remember how mini-series are done. How many mini-series have you seen, where part 1 was not boring or slow?? Part 1 lays background and introduces the characters. This is the traditional method. Even many movies do this.
