I've read many poor reviews of Galactica 1980 over the years, so I was expecting a pretty cruddy show. To my surprise, I actually enjoyed it! Sure, it's more like "Galactica on Earth" than a space show, but that doesn't mean I enjoyed it any less.
It's great to see Adama and Boomer again, and the last episode is really good too. Also, the pilot episode was excellent, as well. Are there some campy moments? Sure. But the original BSG had them too. I found many BSG episodes slow and hard to get through, surprisingly, I got through G:1980 rather quickly.
I say pick it up and add it to your collection!
