One of the few episodes of the original BSG that I think it still good today is the one where Starbuck and the Cylon get stranded on the planet and must work together.
It's the Enemy Mine version of the original BSG
Is this the one from the 10-episode 1980 Galactica season
It was the final episode of Galactica 1980
, which wasn't a season of BSG (despite how it was sometimes syndicated), but in fact a sequel series that was commissioned by the network after BSG's cancellation, in an attempt to amortize the cost of the show's sets, costumes, FX footage, etc. by recycling them in what they hoped would be a much cheaper show. None of the creative staff actually wanted to make it, and there was no inspiration behind it, so it was utterly horrible; so at the end, Larson just abandoned it altogether and went back to writing about Starbuck, and the result was possibly the best episode of the entire original franchise.
