I was expecting the RTD silliness that I'm not too fond of, but I thought the actual episode walked the line very well - the cynical undercurrent goes a long way.
If it had just been a social media satire, I don't think it would have worked, but the pivot into "these people are all naive assholes" was actually pretty successful. In that way, it reminded me of "Voyage of the Damned," in which all the "good people" were killed off by the end.
I had not made that connection - there are definitely a lot of parallels. good catch. Compared with this current episode, I think the peril on the ship was a bit better set up, and there were more characters in that episode that I genuinely cared about.
