Amen. It also harkened back to some of the darker TOS tales where Enterprise doesn't sail off with a happy tune, like Balance of Terror.I thought that was an excellent episode. This show isn’t just the best Trek in decades, it’s the best TV on right now.
I think the one challenge to the planet's plight is that they have space travel and know some people with a bigger truck. They could move.
If my entire way of life depended on sacrificing a kid to appease the local spirits or something, I think I'd move. Or at least expect somebody else to suggest it. and come up with a feeble reason why that's totally not practical.
An additional sign something is jack up with the setup, is how does a civilization develop and advance on such a planet? Odds are good they didn't make it. Heck, for as advanced as they claimed to be, their ships suck, and they didn't know how their own child-sucking machine worked.
But that's my nitpick after thinking about it. I enjoyed the episode.
