So i finished Once Upon A Planet. I liked it. A nice little sequel to Shore Leave. Nice to hear James Doohan as the planets computer. Also kirk finally talked a computer down without destroying it. Lol
I think it's better than the original episode. If you think about it, "Shore Leave" was kind of a shallow story. Nobody was in any actual danger, and the outcome was not affected in any way by the protagonists' actions, since it was just a deus-ex-machina character showing up to explain everything to them. But in "Once," there's genuine peril and the protagonists' actions make a real difference to the outcome.
